sh*t, i'm screwed

[JCell]

fuck, fuxk fuck, so i was driving home and i decide to give it a little gas, i slow down for the first turn, and i accelerate again, second turn come up and I CAN'T STEER, THE CAR TURNED OFF!!!!!, i didn't realize cuz i had the music blasting, i pull over and turn the car on, took 2 tries but it did, then this fucking clunk came from the engine!!! i know other members have had this problem, how did u fix it?, my car is in jacks in my garage right now but i don't know y since i don't know that much about engine problems....


the dealer probably won't cover it since they know of the modifications.... i may try another dealer and try my luck there

i took a video just b4 i turned it off, any suggestions..

Not quite following what happened here?

[Mike R]

Sounds like a valve or maybe a rod knock. Congratulations, and welcome to the club.

[JCell]

there is someting knocking around the engine, i don't know what it is or how it happened, but i'm putting all that i can back to stock and hopefully pass it as warranty

[KYMP5]

yep, doesnt sound good, sorry man. but welcome to the club

[Mike R]

High RPM and turn = oil starvation and bye-bye to the rod bearings. Somewhat common occurance.

[xelderx]

Probably rod knock. When was the last time you checked or changed the oil? These motors are pretty bad about oil starvation in turns and being a little low on oil makes it worse. Several of us N/A's have had this happen. I can't check the video yet since my home comp is fried and my work comp doesn't play video.

[Shane5425]

rod knock to me, i have heard that many times workin at my dads shop.. i vote for the engine starvation on the turns and a bearing spun..

[JCell]

i cahnged it about 1k miles, i'm checking the oil level right now, but i always put 4 full quarts of syntec oil.....

plus after the first turn, it still went, i slowed down to for the second at 4k rpms

EDIT: oil level is about 1/8 of an inch above full

[garretts77]

My car sucked a VTCS screw through the cylinder. Two actually... On its way it crushed the gap of the spark plug and then flew out the exhaust. I know that a few others have had this happen lately as well. Mine didn't do any internal damage except to the spark plug. But they did replace the Intake manifold and fuel rail under warranty.

One more reason to do the VTCS removal and port mod...

Good luck...

[JCell]

can they void the warranty for the rear engine mount?

i can get everything off today except that

Crap!

[JCell]

do u think it'll be alright to drive it to the dealer, about 30 minutes away, or should i tow it?

[garretts77]

Well mine was running on 3 cylinders, so I wasn't driving mine. I don't know about yours but 30 minutes seems like quite a ways if the car is broken... Maybe take the spark plugs out and fish around in there with a magnet? somebody in one of those threads that I posted mentioned that he pulled a screw out that way... Just don't lose the magnet in there too...

[garretts77]

Oh and BlkZoomZoom says it is from the VICS, not the VTCS...

[03promaz]

If its the VICS...I will be in Clermont, and Vero Beach in a few weeks and will help you do it. Thats only if you could go without it until then. Took me a total of 3 hours to do everything on my car.

[Brian MP5T]

Get Mazda to tow it. Should be part of your "Roadside Assistance" Plan unless that was only in Canada...

[pdhaudio83]

you might want to delete this thread before MazdaUSA reads this...

[pdhaudio83]

is this your daily driver?

[Brian MP5T]

What "MODIFICATION"

[FunkyBuddha]

Sux bro... what rpm were you at when you did this turn?

[JCell]

at about 4k rpm.....

while i was checking the engine, i took the spark plugs out, all were fine except number 4, which was burned and smashed, no gap at all.... it's too late to get a new one right now so i'll let mazda deal with it


BTW, this is my only car, hense daily driver, and does Mazda really check threads?...

[pdhaudio83]

rather be safe than sorry, and yes they do. they could save $5000 right in this thread- it pays for them to.
sounds like you have a big problem.

[JCell]

with my luck, they'll see it too

plus i won't be able to go until mid next week.....

[pdhaudio83]

i'll have a block for sale here pretty quick (installing a built one march 11) its running good for me if you are interested.

[JCell]

the engine or just the block?

i think my problem is mainly in the heads...

[protegerider18]

It sux Mazda reads our threads like this. I get uncomfortable asking questions since I really don't want to take my Mazda in for service and they tell me they are going to void my warranty for something stupid. I will be glad when my warranty is up. JCell how many miles u got on ur Pro? It seem really odd for your motor to go like that. Mazda should pay for it.

[pdhaudio83]

with that kinda of noise, i honestly think its more than a valve- thats a LOUD LOUD noise. where is spicymc? he would know...

just dont put your name or license plate on a picture, you can always take them to court and say thats another person car..

[mazdaspeedpower]

exactly..so long as A) you never confirm a modification to car, or show a picture of it, or B) Never use real name, or plate number. C) show anything identifiable to your car, something unique...like a sponge bob thing, or whatever the fuck you people hang from your mirrors...which by the way is a bad thing to do since its a distraction to you and other drivers!.

[03promaz]

I dont care if Mazda reads our theads. I already told a service manager to shove his clipboard up his as. Then the next day walked into the parts dept. with my intake manifold to show them that the VICS can really fall off. I'm pretty sure that dealership wouldnt service my car under warranty ever. Besides retarded ass dealer mechanics always scratch my paint.

[justanotheradikt]

i had something close to the same with my pro.....something in the intake let go and somehow got the sparkplug to get cut off and drop into #4 which caused a lot of damage...my car was towed to the dealership(paid by mazda) and a brand new motor was put in it....but my car sounded a lot like your video did...but ran really rough every few seconds...does yours do that?

[protegerider18]

Is this known for 03 proteges I all the people that this has happened to have 03 Proteges. Maybe it will happen to me. Then I can get a new motor.

[justanotheradikt]

protegerider18 do you still have your original intake?...because your intake will void the warranty and they wont do anything for you.

[PhreakV]

delete this thread, JCell... better safe than sorry. (dunno)

[wannabe]

hey garretts77 was the rattling you were experiencing at certain rpms or all over the place? i have a bad rattle i ust assumed was a loose gasket somewhere along my exhaust...but now im thinking it might have something to do with my VTCS/VICS...

[protegerider18]

I still have my air intake but my custom one is just a cone filter on the end of the MAF sensor

[garretts77]

Just try to imagine what a screw or two bouncing off of the piston would sound like. Even at idle, those things are moving pretty quickly. It rattled at every engine speed until it finally got blown out of the exhaust. One happened one morning, the rattle was pretty bad, and there was hesitation. I drove to the dealer and it was still doing it for the service manager. But the techs couldn't make it happen, and they sent me on my way. The next week on the freeway as I was accelerating from the on ramp, I started misfiring and decelerating, the CEL came on and flashed at me, and I parked it at the dealership.

[wannabe]

well that makes me feel a little better. mines only rattling at certain rpms. so it probably is just my header or something whew. i was scared for a second there...

[JCell]

so i got the car back and the tech says that the butterflies had come lose and was making the noise, repaired by new intake manifold, new injectors and new fuelrail.....


i'll probably open the valve cover just to make sure it's all good inside

[Sveivo]

so i got the car back and the tech says that the butterflies had come loose
So did anything get into your cylinders, or did it rattle in place somehow?
Also, how many miles do you have on the car?

[pdhaudio83]

close call! glad to hear. warranty, correct?

[Mr. Win]

wait... they didnt do anything about the spart plug that was slammed shut?

Why? That's not going to show you the combustion chamber.

[pdhaudio83]

yeah valve cover removal somewhat pointless since you cant see the mani runners even

[Kooldino]

DiS has what sounds like this exact problem. I just called him and told him about this thread. He's all pumped now. :D

[JCell]

well, the headers r going in this weekend, so i'll know if anything went thru, and teh valve cover is just to be sure

[chuck]

'

[DiS]

hOOOOOOOOOoooooooLLLLLLLLLLLLLLLLLLYYYYY SHIT!!!

AS Kooldino said, I HAVE THE EXACTLY SAME FUCKING PROBLEM!
My car is at the dealership right now, and as I said in my 5th thread about the clunk, mazda service manager called me about 2 hours ago and said that tech is taking intake manifold off the car to see if anything is missing........

I had this shit happen fucking 5 times!!!!!! 1st dealership refused to do anything so I just told them to go fuck themselves and called MAZDA USA, and then went to dealer where I originally bought car from (thats where my car's at right now).

JCell I really appreciate you taping that noise on video camera. I have a vid. camera too but all those times when I had clunk, it clunked for like 2-3 minutes and then stopped. BS! Thanks again.

[Kooldino]

well, the headers r going in this weekend, so i'll know if anything went thru, and teh valve cover is just to be sure

Again, why? You'll just be able to see your cams and buckets, really. What could it have done to them?

[chuck]

I don't beleive that butterflies were making that noise! I beleive the screws were making the noise.

I beleive that yes the butterflies were loose but the screws from them came loose and fell into the combustion chamber and were bouncing around causing all kind of damage and even damaging sparkplug.

I could see possible valve damage not a good seat........lost of compression.........I would go get a compression test done.

[Mr. Win]

heh if he wants to do it just let him... like i said id be concerned about your plug that was slammed shut..

yeah, i've been reading about ur situation too, hopefully they'll take care of it the first time. r u going to show the vid to the dealer?

[DiS]

yea dude I hope same too. As far as the video, if dealership has internet access, I will definetly show them the video. Although at this point, tech is taking the mani off anyways so Im sure he will find few things missing.....but I will definetly try to show the the video......speaking of which, since I bought 1GB USB flash memory stick, now to come to think of it, I will definetly show it to them

[03promaz]

My butterfly screws only left a few scratches on the top of my pistons in #2 and #4. I used my bosses scope to view the cylinders.

[JCell]

u would think that after soo many people have had troible with this that there would be some kind of recall....

[DiS]

once my problem will be fixed, I will write a letter to MAZDA USA and current dealership, saying thanks for all the help, and suggesting that they should issue a recall for '03 models

[ahb11m]

but there is a fair amount of work involved in that change out...

a few engines, and a few that run bad....

or wait until the warranty is up... its not as if they have anything to look after as this car ain't being sold anymore

[protegerider18]

Thats a good idea to write a letter to Mazda hopefully they will look into a recall.

[chuck]

Or at least a TSB, so we know the years involved and have some proof.
I don't think they want/or will do a recall.
Look at all the TSBs they had, even some really bad ones, that they still had no recalls.

[DiS]

So far I know only of 2003 model sedans having this problem and not others. Not even 2003 P5s, MP3s or MSPs. So it has something to do with sedans (DX, LX and ES)......weird, but as I will pick up my car tomorrow I will write a letter...

My car was at the dealer since past Monday (today 4th day) Im already missing it!!!!!! 2005 Corolla XRS is fun to drive especially at 7k rpm on highways (8k rpm is redline) but I wanna my baby back!!!

Mine is a 5...

[03promaz]

My VIN is a 1 so made in Hofu. I wonder if the dealership is smart enough to check all the screws or just the ones on the butterflys that came loose. I mean they could fix example #'s 1 and 4 butterflys but in a week the #2 could fall off and you would have the same problem. My #1 and #4 fell off but I took all of the butterflys off and used loctite and peened the ends so they CAN NOT loosen up again.

[DiS]

dude, they are not fixing the butterflies....they are replacing the entire intake manifold with a completely brand new one, so everything will be like butter (thumb)

um also, you removed all butterflies? WTF I hope you didnt remove those from VICS, and if you did that was really stupid because VICS actually serves good purpose. VTCS is actually pointless on our motor. I hope you removed VTCS butterflies and not VICS.

[ahb11m]

so if these cars are all ones, that could indicate an issue in the tofu plant

i wouldn't of thought it would be specific to sedan or hatch, but rather to engine size, and aspiration... engine is built and dropped into the car body...

so its an issue in 2.0l NA engines? yeah??
worthwhile knowing this... are they all manuals?

[03promaz]

Ok so they give you a whole new manifold. They are putting the exact same thing on. What says the new mani wont do the same thing. I think they need to address this issue more serious. Yeah they dont make the car anymore, but the motor is internally falling apart. We pay attention to sounds and the way out cars act. What about those people that dont care or dont realize when something is wrong. 5 years old and needs a motor b/c it fell apart and blew itself up. Doesnt make sense to me.

I NEVER said anything about leaving mine off. My VICS fell off so I took everything off and put them back together so it cant happen again.

[justanotheradikt]

ha i got a whole new motor out of mine...it tore up too much stuff....when i get home ill look at my vin...oh and yes someone asked about if they were all 5pds i think? mine is a 5spd.

I emailed Mazda asking if they have any problem with this issue and they replied that there is not a problem with butterfly screws being sucked into the engine. But they did say they have documented a concern with the Product Planning department and Quality Assurance department for review.

[JCell]

not all blue........does my car look blue in my sig?

[sampson]

could this be my problem?
i have an mp3 that makes a clicking sound after the car gets over about 2300 rpm. if you are easily accelerating or holding a constant pedal position while driving, it does it. but it stops as soon as you let off the gas pedal or accelerate quickly. i dont understand the whole vics/vtcs well enough to troubleshoot this for myself. any input is appreciated.

[DiS]

hmm dunno what to tell you dude......check out the video in the 1st post of this thread that JCell recorded. Sounds like you might have a different problem but I could be mistaking. More info please

[sampson]

i tried to watch the video but it would not work for me. pretty much that is the whole problem. i have taken the car to the dealer 2 times complaining about the clicking (drives me nucking futs!) and the first time they said they replaced a cv shaft which had a cracked boot which they claimed stopped the clicking but it did not. i took it back again and they told me that i was 2 quarts low on oil. 2 QUARTS!!! i had just changed my oil a few days before and i know it was not leaking out. wtf? they said they added oil and it stopped. it did stop but for only a few minutes. argh!! they also mentioned something about there maybe being a lifter problem. i dont know!!!

[ahb11m]

umm
yeah i was joking about the colour


anywho i'm off - grand prix is on!!!!

[03promaz]

Lifter would be my guess. What kind of oil do you use? Some cheaper oils that Auto Zone sells (Coastal, ValueCraft) suck and cause an oil pressure problem. At our shop we used Coastal b/c it has a pretty good name, but then we had a few vehicles have the oil pressure light flicker. We swapped for some Castrol GTX and its gone. That 20 cents a qt difference is worth it.

[DiS]

I dont know who says that this is common, but Ive worked on alot of cars (nissans and Mazdas in particular) but this is new news to me. I know of only about 6-7 people, but this issue definetly has to be addressed, and when Ill be picking up my car this Tuesday from the dealer, I will let them know that Im not the only one with this problem. I will direct them to this website to show facts and also will show the video of clunking noise, that JCell recorded.

[glyph]

Well, I just got finished putting my turbo kit in, have run the car a total of maybe 30 minutes by now, and I get a very similar sound, but mine is very fast compared to JCells. Heres a link to the vid 5.5mb. Think it's the same thing? I am going to take my intake stuff apart again to see if it's one of those screws. It sounds loudest right around the crank pulley.

rattle vid (http://www.jonathan.allain.com/vids/rattlerattle.avi)

[03promaz]

Around the crank pully?? Mine was at the top of the motor(since a screw was in the cylinder) I would def. check that out ASAP.

[Shane5425]

that doesnt sound like the butterflys, that is one constant sound, doestn change at all in pitch or anything, take a plug out and see if its smashed, and lookin the side the cylinder, use a pocket magnet and see if you can get a screw out..

[JCell]

it's definitly not the same kind of sound, but it's there, the sound could be different due to the turbo or maybe cause it's a 1.8

i think mazda will notice that the engine is not stock so warranty is out, definitly check the intake manifold

R any of your plugs damaged?

[glyph]

Around the crank pully?? Mine was at the top of the motor(since a screw was in the cylinder) I would def. check that out ASAP.
i'm going to take off the intake to look for a missing screw.

[glyph]

no warranty left, 6 years old. i'll check the plugs.

[Shane5425]

if the screw made it into the cylinder, just use a pocket magnet to fish it out , if you come out with a screw then you know that that is the problem..

[glyph]

how do i get into the cylinder? from the intake port?

[JCell]

take the saprk plugs out and use a long reach magnet to get in there

[glyph]

ah i have one of those

[glyph]

hanging on the fridge door in the garage even

[glyph]

nope, no screw. thoere wasn't much room in there... those things are small

[Shane5425]

i dont think it is a screw then, you have something in the bottom end comming apart, if it were a screw ti would be makin noise in the intake and upper head, no tthe lower end of the engine, i am betting on a rod problem

[glyph]

thanks, great news! how does it just start suddenly?

[Shane5425]

boost..

[Shane5425]

i would start by takin the intake mani off and check that, if that is all good, pull the pan off and check the bearings..

did u put enough oil in the engine, you gonna have to put a bit more than normal to compinsate for the turbo..

[DiS]

thanks, great news! how does it just start suddenly?

1st of all, is that sound rpm-dependant? When u rev the engine, does that sound get faster? If so, then u would have the same problem as me....the butterfly bolts, but ive only seen people with 2.0 engine 2003 model Sedans having this problem. Pull ALL of the spark plugs and check them if theu are smashed or not, and also check for gapping on them.

[JCell]

did u push it hard during your test drive?

he just checked the cylinders with a magnet and nothing is inthere, i think the next step would be to remove the intake mani..

[DiS]

i didnt suggest to check the cylinders. I said to check the plugs. My friend (mazda mechanic who was working on my car for 2 and 1/2 weeks) at 1st said that my head walls are fine, and then 2 weeks later tells me that i need a new head because mine was all scratched up. It never hurts to check twice, even though I wasnt suggesting that, but still a good idea. Hmmm

[glyph]

i got it to 3000 rpm in neutral on the ramps in my garage, kept it there for about 10-20 seconds, then quit. The only driving I have done was real slow from the driveway to the tow dolly, to the exhaust shop, then back. I checked all the spark plugs, regapped them to 0.43 (from the service manual), they were nice and snug there and no apparent damage. Brand new iridium plugs with some black soot on them. I put 4 quarts of fresh Mobil 1 oil to compensate for the extra lines and a bigger 626 filter. Normally 3.5 qts. I fired it up again, and same sound. I got underneath and it kind of sounds like it's coming from the AC compressor (which isn't engaged), but above it sounds like it is coming from the belt area. I will check the intake section, and if I don't find anything I will check the belt area with the valve cover off, and see what I end up with. I haven't revved it since I heard the sound, and am rather scared to.

[DiS]

is the sound rpm-dependant or not?

[glyph]

one of those built motors from MAM is sounding really good about now... I can't get into this thing tonight, I will have to do it tomorrow. Maybe I'll cut out of work early or something.

[glyph]

boost..
I haven't actually seen any boost yet, just momentary spikes to 0 pressure.

When you say check the bearings, I can see them with the oil pan off? and what do I check for?

[glyph]

find someone that knows how to build engines to check it, once u pull the rod caps off you have to tourqe them back down to a spec

if you still decide to go on, you have to see if the bearings are locked n place or did they spin around scaring the crank and rod

before you do that, take the intake mani and see if any screws are missing..

actually, it doesn't seem to be. There is slight variation when I back off the throttle, but the engine accelerates normally (well, normally for the minor tuning I have done). I did slow increases to 2000rpm or so, and it didn't seem to follow. Please tell me this is a good thing. I will sleep a lot better

[JCell]

mice was definitly rpm related, as i reved the car up, the rattle increased...

bent valves. i let beau listen. when did it start? AIM me!

ouch.. better than a bottom end problem though.. now that u say bent valve, it does remind me of one..

[DiS]

ok, Im guessing from your explanation, the sound didnt get faster after you started revving (even slowly revving) thats a good thing because I can say that you do NOT have bolts missing. Got me there now. Definetly should check few other things.

[glyph]

i must have let something get in there. Shit baskets. AIMing you shortly.

[pdhaudio83]

it sounds exactly what i had, in which case, the car will run and accelerate normally, however, you might break the valve off, which would mean a new motor.

worse case: if it is a bent valve, you might need to find a new head.

or just have his head reworked with new valves..

there is a good machine shop around here, but i'm sure it will be pricey

according to Beau at MAM, it's a valve. I got him on the phone and put it near the engine. He said if it was rod knock it would be affected by pulling the injectors one at a time and seeing what happens. That combined with not matching RPMs says its a valve. Fun, eh? I must have let something get in there, but I have no idea how.

I have to get hold of a borescope somewhere. Think the mx folks on base will have one they'll let me borrow? it's only air force property.

[pdhaudio83]

its possible a valve damaged the head, and depending what happened, it might not be worth it to fix the head. new good, SS valves are $20/ea IIRC

[glyph]

Will the head have to be machined to fit one new valve? If I get a whole new head will it work with all the old valves? Basically, what am I in for? I have no idea what any of this will take.

I am thinking of ARP studs while I'm at it, possibly a port and polish? If the thing is going to be worked on anyways...

Let me join the club.

Here is my situation.

I've installed the msp turbo kit in my car about a month ago.Everything is running fine until last week. The car won't idle correctly and I heard this tinking noise come of from the engine. Also I don't hear the turbo sucking air in, so i read all the stuffs about the VICS screws(cyc #3) came loose. Open up my intake mani, found one screw and the plate came off. Check the spark plug, (cyc4 bend) regap
it and put the car back together. Start the car and the
it still won't idle and I guess the other screw is in the exhaust portions. mani or turbo I don't know. So I have
to take off the turbo the week and find the other screw.
Also I drive the car around a little be and it sounded like
police siren coming out from the engine bay.

So I won't like to confirm
1. What is causing the rough idling issue
2. Sometime the car won't start right away. I have to crank
it for the a few secs.
3. What are the chances that my turbo can be destroy by
that screw.

Thanks

... it sounded like police siren coming out from the engine....

It sounds like it already is. (headshake

[JCell]

yeah dude, from the moment u realized a screw was gone, ushould have stop driving ur car


i wish u luck dude

[Wrxtasy]

Yeah but I didn't know. Oh well going to replace the turbo
with gt28r

[garretts77]

Lock-tite the screws in VICS so you don't destroy the disco poe-tay-toe...

Might as well port the IM and remove VTCS while you are in there....

[glyph]

I only have the VICS, I don't have the VTCS in mine. When did they start doing that? 2.0 engines?

What are all these references to the disco potato, anyways?

[garretts77]

Yeah, 2 liter engines have it, except the MP3.

I first heard about the disco potato in Sport Compact Car a couple of years ago. It was supposed to be this crazy turbo that somebody at Garrett came up with. At the time, Garrett still wasn't making it yet, but they had a prototype inside some crazy looking sentra with color shifting paint that they called the disco potato. they put the gt28rs in it and the name stuck with the turbo.

[FlyinHawaiian]

heh, I joined the club too, and that's the exact noise my car was making after oil starvation, just not as loud... Can you say engine replacement?

If you wanna know what happened here it is:

now I know about the disco potato.

Flyin, I checked that thread, good luck, man.

[Shane5425]

ever find the exact problem?

[glyph]

not going to know until the old head gets to beau and he diagnoses it. I don't want to take out the valves with my lack of know how, plus you need certain tools I don't have. 2-3 weeks. I will post when I find out.

[SoonP5ismine]

im having the same problems with my car now (03 protege5). look below for link to my videos and pics. sound very similar except mine seems random rpm. but i did take the intake off and the butterfly was loose and 1 screw was missing. i didnt find the screw yet and hoping i will by the time i put the engine back together. waiting on gaskets now and will put the intake back in this weekend.

here is the link to my thread that has large pictures and video.

Your screw is probably wedged in one of your catalytic converters.

[lil_red_wagon]

sounds like a dropped valve
