Corrugated EGR tubing?

[Kooldino]

I recall someone posted a picture in the past where they used some kind of corrugated metal hose to use as their own EGR pipe, complete with fittings and all. Does anyone remember the post/have more info on what to use?

[mspHtown]

could have been tekkie.

[Kooldino]

That's what I was told, but I couldn't find the post to save my life.

thanks for starting this thread ForceFed :)

I finished the install last night, but I have a small vacumn line isssue, I think when I clamped down my brake booster I did it to hard and crushed it :(

but regardless of that I got the car all fired up and its running, not running good though because the emanage does not see the vacumn

but I will be fixing that tonight and posting up the completed project :)

obviously with the vacumn line problem I could not drive it but that should be a quick fix

And for the EGR I came up with a different plan if it works which I think it will its a cheap fix, its a stainless steel gas line for a dryer, fireplace etc. I dont know how well this will hold up against the heat but I think it should do the job, and its nice and flexible so installing it is way easier than the EGR pipe.

this is a pic as an example, the one I have was just a couple inches longer than the egr pipe so it fit pretty wellhttp://i1.ebayimg.com/02/i/05/11/85/a5_1.JPG

[Kooldino]

More of tekkie's pics...


here is what you need, left side 1/2" flare, right side is 5/8" flare on the top one, and 5/8" on the bottom one, the pipe I used is 1/2" SS

[baconbitz]

I think I might have to try this, im tired of my cel being on all the time. Gotta clear that code and my second o2 sensor code.

[_Slotegé_]

I thought ProtegeGarage Sold an EGR tube?

Do you have to get one of his manifolds in order, to buy a tube from him or something?

[ForceFed]

Damn..I was gonn tell you its gas line...Oh well.

[KzA]

yea, Im gonn have to do this as well, right now my exhaust mani is tapped with a hardline running from the tap into a silicon material tube with a clamp...it leaks like hell...

[baconbitz]

Protege garage sells one, I have their manifold but I didnt get the EGR pipe. If this works though its a cheaper alternative. Im going to lowes tomorow to pick up the parts. As long as its not raining ill probably get it on tomorow.

You can get the EGR tube from him, but the corrugated piping could save you a lot of time and aggrivation. Trust me.

Not sure if lowe's carries the parts, but if they do, post the part number and such here.

[ForceFed]

Not sure if lowe's carries the parts, but if they do, post the part number and such here.Lowes and Home Depot both should carry the Gas piping.

[Kooldino]

product Link?

[baconbitz]

I just got back from lowes with the tubing. I bought a kit that came with the connectors I needed as far as i know. Ill let you guys know how it works when the car cools down and I have a chance to get it on. I found it in the appliance section at lowes.

Sweet I'll take your word for it!

If you could list a parts list/part number's after you get everything sorted out that would be awesome!

The 626 IM will be one of the next mod's that I do to the car.....

Thanks

[baconbitz]

I went out and discovered that one of the connectors that came in my kit is just a bit to small so im going out and buying another connector tomorow.

[Kooldino]

Post info when you have it. Thnx.

[djarkitek]

subbin, def intrested in this. it was a bit switching out the egr pipe when i got it with the pg im

[GhostMercury]

yes post this info with parts numbers, because it will look bettr and make the mani instal much easyer

[baconbitz]

Will do. Ill get a pic of the bag it came in right now actually.



EDIT: Picture is up. I got the 48" one because thats all they had, it reaches with a good amount extra. I sized it up earlier today. Ill get more pictures when I get the tube on tomorow.

[GhostMercury]

are there different diameters for it?

[baconbitz]

Not that I saw. I got the 1/2". I havent had time to go back to lowes today, been real busy switching dorm rooms. Ill try to get up there soon.

[boostdprotegelx]

sucks to be me..i'll have to block mine off..i dont' have anything on my manifold to allow for this tube....:(

CEL forever FTL

[GhostMercury]

what do you mean you dont have anything on the manifold to use this tube? di you block it off already

[boostdprotegelx]

what do you mean you dont have anything on the manifold to use this tube? di you block it off already
it's a custom manifold. check my thread.

[GhostMercury]

o as long as it isnt the 626 manifold. cause then i would be confused

[boostdprotegelx]

o as long as it isnt the 626 manifold. cause then i would be confused
i'm talking off the turbo manifold...it's custom.

[GhostMercury]

o you meant the turbo manifold. hehe. now i totally understand this lol

[Kooldino]

A 36" length should work, right? That's the best looking length I could find.

Could you take a pic of the tubing and the threaded ends? Did they thread right in, or did you need adapters?

[baconbitz]

I needed adapters for the ends. I went today but ended up buying the wrong sized adapter for my hose. Ill try again probably sunday or monday. 36" should be plenty. As soon as I can get to a hardware store (im going on vacation but bringing the car) ill get some pictures. Not sure if I will have internet or not so it may be as late as next saturday before I can get them up. Ill do what I can tho.

[baconbitz]

Sorry its been so long guys Ive been really busy lately. Im still going to try and get this figured out, I just have to head up to lowes and find the right fitting. As soon as I do that ill see how it goes and if all goes well Ill do a write up.

[Kooldino]

Word.

[boostdprotegelx]

Word.
block mine off.

[mazdaspeed777]

So has anyone confirmed if this SS corrugated tubing holds up?? Also how does the tubing connect to the connectors?? Also to get this straight the side that connects to the IM is 5/8" and the side that connects to the headers are 1/2". Is this correct??

[03promaz]

subbing

[Kooldino]

block mine off.

Aye

[mazdaspeed777]

Wooohooo! I just went to home depot and picked of a SS gas stove line and it already came with three connectors that fit perfectly to the headers and IM! First try! Score! So now I just need to figure out where to run it through the engine bay since it is 48" long(the only one they had). So this will fix my thermal spacer problem and make it way easer to take the IM off in the future.

[Kooldino]

48" long? Geez.


Post a pic and a part number while you're at it. :)

[ProtoType5]

Nice Score...I've been thinking about this since I had my fiasco with my EGR....Hope it holds up to the exhaust temps...

[GMalatrasi]

Post a pic and a part number while you're at it. :)

+1

[mazdaspeed777]

Ok well I am not sure witch number is the part number on the package but there is a number on the lower left hand corner of the front of the package that is: PM15X103 and the bar code number that is on the back is: 84691 80497. The product is made by GE and it reads: "Universal 48" gas range installation kit for all brands", and it is in a clear blue and orange package with a picture of a kitchen stove on the front. I got it from home depot right next to the appliances(not the plumbing section of the store).

[mazdaspeed777]

And here are some pics of what it looks like so far:

lol yah I had to. The sucker is 48" long! And maybe that will give some time for the air going through the EGR tube to cool off a little.

Keep the EGR pipe hooked to your intake mani, and cut it short so that there's only about 9" of pipe. Stick a breather filter on the end, and your CEL is gone. THat's what I did. Worked liek a charm for months. You can see here my breather filter that I put on it, just under the water neck.

good call. KOOLDINO, DO IT.

[Blackrose]

If these pipes are stainless then they should be all good to hold up against the exhaust and heat right?

[Maxx Mazda]

good call

Miller time?

[mazdaspeed777]

anyone want to buy my stock P5 EGR tube??

[Tzar177]

Bump! How is this working out for those who have done it? Thinking of maybe doin this when i install my header

Heck yes. hahahaha

When I did that, my car would wig out within the first 2 miles of driving every time I drove it.

Wierd... Mine ran perfectly. I actually got the idea from another member (forget who but yellow P5 turbo) and he also had no problems with it.

[baconbitz]

I am a lazy fucker. I still havent gone up to lowes to get the fitting I need. I keep getting the wrong one :(

[Crazee D]

Wow, I was lookin all over for this! Thanks man.

I had to bust off the stock EGR when we tried to test fit my 626 mani.
Mani fit but the EGR tube with it did not no matter what we tried.
Then we found the fuel rail didn't mount and the injectors did not set properly in the mani and removed it.
So I ran for 5 months with a copper tube connecting to the EGR but not snaked thru the stock way, just looped from the side.
I didnt heat shield it and it melted thru some wires. So its sheilded now!
I was searching all over to find the place I read about that dryer hose flex tube.

thats allowing un-metered air in, leaning out your motor when the egr is open i'm thinking connecting it back to the intake after the MAF would cause less problems since you're only letting in air that is metered. i might give that a shot when i get back home. can't wait.

If the air was coming from the exhaust as stock, how is it metered anyway?

Not that it matters, my car will run without a MAF at all...

[Kooldino]

If the air was coming from the exhaust as stock, how is it metered anyway?

It's not, but it has fuel in it.

Letting clean air into the motor that is unmetered will lean it out. If you allowed metered air into the EGR, it would behave.

[Maxx Mazda]

Disagree. In closed loop (which you are in 90% of the time) the car tunes off the primary O2 sensor's reading. AFRs will nto be changed regardless of what type of air is being let in. You guys are overthinking this concept. Engineer in your spare time? :D

No, first hand experience. When I ran an open air EGR, the car leaned out big time. The O2 only has so much influence.

Any gain to this? or just a preference thing?

[Kooldino]

Preference thing.

Removing your EGR is a bad thing. Only do it if you have to.

[Action Jackson]

I had to replace my EGR tube with another stock one.

Not fun esp. the part near the throttle body. What a PITA. It's a 25mm in a not too spacious location! I had to stand in the engine bay and crank on my cresent wrench!

Anyone try the corrugated for more than 500 mi? Tekkie told me that's all he had his on for.

[Tzar177]

So has anyone confirmed if this SS corrugated tubing holds up?? Also how does the tubing connect to the connectors?? Also to get this straight the side that connects to the IM is 5/8" and the side that connects to the headers are 1/2". Is this correct??

[Tzar177]

i went to lowes and couldnt find a gas/dryer ss line or any of the fittings i would need. i did see tho ss faucet lines...dunno if there the same thing, but then again i seen no fittings anyway

[mazdaspeed777]

They have them for sure at Home Depot, thats where I got mine and it fit perfect. This is a good mod to do if your putting on headers or removing the intake manifold, it makes it way easier to remove them.

Also I have had mine on for probably over 4,000 miles now and it still looks and works great. It does change color because of the heat but thats about it

man this is wha i been wantin to do, but sum ppl told me its not a good idea, so i been unsure... plus i'm a rookie so eh, but if doin this will lean it out isn't that better seeing how our cars run rich as it is (or am i wrong)... either way i'm gonna give this a try, if there are any problems i'll just go to home dep and buy the gas/dryer pipin and reconect IM to header...

[Maxx Mazda]

Ya man I ran like that (and still am, albeit my EGR is completely disconnected) and no problems at all. I have standalone so I can remove my EGR, but if you disconnect it completely you wil lget a CEL.

[boostdprotegelx]

it didn't work for me...that's why i have a cel...

[Maxx Mazda]

Wierd. It seems to be hit and miss with this. A few people were running it like me with no CEL.

[LX_StreetGlow]

well hopefully next week i'm try wat you did, and cut it short and stick a breather filter on the end, if that dont work i'll just go to home dep

[808MP5]

Howz those SS Lines holding up... Yes Tax return 626 and SSAFC here i come...

[mazdaspeedwerx]

the gas lines are fire rated up to whatever degree so they cant melt when there is a fire in a house. there should be some kind of rating on the sticker attached to it. I thought about this but I will likely use copper tubing so it looks a bit better.

[blueprotegelx]

i just went to home depot to do this mod. the kit i bought is a water heater kit. both ends are 1/2" and all i need to do now is get a female 1/2" w/ a 5/8" male end fitting to connect to intake mani correct?

[blueprotegelx]

just did this mod! pretty simple, only pita was connecting fitting and hose to intake manifold b/c of the coolant lines but i got it!

[808MP5]

I'll be doing this very soon... Just waiting on fuel rail o-rings and other asscociated injector gaskets

[808MP5]

tip for whoever attempts this... make sure the tubing isn't touching anything... i didn't notice it was touching my engine harness... and now it's kinda burnt (some wires are exposed)... Lucky me the car still runs... Unlucky me im in the market for a new engine harness

i'm kinda curious if this is reason my fuse for cluster keeps blowing???? every since i put the hosing in the fuse has been blowing. i thought i fixed it today but i didn't. maybe this is why????i know it's touching contacting the block

edit: i just found 4-5 wires melted. they connect to transmission. looks to maybe be ground for speed sensor etc. hopefully i can fix them tonight and fix my problem.
-fixed the wires and routed tubing..thinking about getting some heat wrap and doubling up to prevent this again!

[808MP5]

yup.... very tricky stuff.... i gotta cut and rewire some wires to make sure the connections are good... burnt a total of 6 wires, 4 which definently need repair. some heat wrap is a good idea.

[magnumP5]

Sub for possible use with 505zoom's intake manifold. I'm glad I finally found/was directed to this thread. So just to ask the same question everyone has been asking: have these been holding up well over time? Looks like I might have to hit up and Home Depot here soon...

[MS_Rick]

^ double up!!

[808MP5]

about 6000miles and all is well

[i like speed]

subbin too.

[SIBalla23]

How much of a pain was it to remove the egr tube from the car? Can it be done while the intake manifold is in the car? I really don't want to pull it off.

[SIBalla23]

Also what length is good to run? 48" is to much, so is whats a good length where you won't have to much extra?

[Not Jo3L]

looking at doing this with the install of a intake manifold spacer. I have feelings the EGR pipe wont meet up to the EGR bung on the headers I have, so to make the installation easier...I might as well go with a flexible gas line.

[808MP5]

Good luck. Painless install just heed previous warning

[Not Jo3L]

I will take warning to that. What are the sizes of the connectors needed 1/2"?

[808MP5]

there's the exact home depot part# in one of the first couple pages. It comes with the fittings needed

[blueprotegelx]

I think this should be posted as a sticky in the how-to as it becomes hard to find.

[JCell]

^^^ thanks for the link bro!

[blueprotegelx]

not a problem, easy and efficient mod.

pics of setups?

[ProtoType5]

Bumpage for needing to be moved to Necessary information.

[destineal]

Bump!. I'm gonna try to go with the 3/8" instead of the 1/2" piping. We'll see how it goes.

[justanothermp5]

sub, this thread is fucking difficult to find

[destineal]

yep

[destineal]

I just measured the EGR as best as I could and its around 18" give or take.

[dmention7]

Okay, I feel a little dense here, since so many other people have apparently been able to figure this out... but I can't for the life of me find a fitting that will fit the intake mani. It's a 5/8" thread with an 18 thread pitch, but every fitting I can find is 14 thread pitch. The closest I could find was the male part of a compression tube fitting for 5/8" OD tube, but the diameter was about .040" smaller than the threads on the EGR tube. The thread pitch was correct, but the threads only engaged at their very peaks.

Does anyone happen to remember specifically what type of fitting they used at the intake mani side? Compression, Flare, MIP, NPS, NPT, BPST???

(dunno)

[Sleezer1533]

The fitting I used came with the line

[dmention7]

Was it an exact fit? I got a 5/8" MIP adapter with my line, but the thread pitch is 14 instead of 18. I can thread it in about two turns before it siezes up. I'm wondering if it'd be easier to just get a tap and tap new threads.

[Sleezer1533]

This is the fitting that came with mine

http://i787.photobucket.com/albums/yy154/Sleezer1533/DSCI0024.jpg

[dmention7]

Bump for a little more info on what fittings people used...

[Sleezer1533]

The ones in the kit people

[dmention7]

None of the fittings in the kit I bought are the correct thread (or type of mating surface for that matter) for the EGR port, that's why I'm curious if it was an exact fit or if people are just wrenching in the 5/8" fittings even though they're the wrong thread pitch. Seems like that would give a pretty crappy seal to the exhaust gases, but if it's working for other people, I'll give it a shot.

[destineal]

I'm having trouble routing my corrugated tubing without it touching wires. Naturally, I don't want to melt my harness wires, so I need options. The easiest thing I can think of, would be to heat wrap the corrugated egr tube. My only concerns are that the pipe won't last long wrapped and that the pipe still might be hot enough to melt wires. My other option is to instead wrap the wires/ coolant lines.

[Sleezer1533]

Mine dont touch. There was just like two places where I used a metal zip tie to hold the tube away from wires. To be honest the pipe really only gets hot enough to be concerned with for the first 4-6 inches after leaving the header. At least thats as far as the yellow coating flaked off, seems the heat dissipates after that.

[HKPRO5]

I ended up capping the header and adding a breather filter with the EGR pipe to the IM.

Are you boosted? What size did you get? I got 3/8" x 24".

[destineal]

I think I will try that hkpro5

[Sleezer1533]
