Stiffen your Mazda 3 rear engine mount - for $4

[flyrevs]

I just got a CB Mazdaspeed 3 and there is a bunch of wheel hop and excessive engine movement caused by the rear engine mount design.
I read all of the posts on how to fix this by spending $90 and replacing it with the AWR mount with urethane bushings. I took the rear engine mount off to examine it and discovered that the main reason it is so bouncy is because it is only partially filled with rubber.

Engineered slop: (circled in red):http://natattacks.com/dad/comparisonenginemnt.jpg

Before I shelled out $90 for the AWR I thought I would fill the gap and see how it performed. I bought a tube of 2 part - 6 minute epoxy from Lowes for $4. This stuff has a rated strength of 1900 psi so it will definitely hold up.

2 part 6 Min epoxy - Lowes $4:
http://natattacks.com/dad/loctite.jpg

I put tape on the back side of the mount to contain the epoxy. I mixed the entire tube of epoxy and poured it into the mount. 1 tube of this is all you need. It flows just right and entirely filled the gap. In about 3 hours it is rock hard (let it setup in a heated area). I installed the engine mount and took it out for a spin.
WOW!!! All the wheel hop is gone, the shifts are now "crisp". :) Best of all: NO engine vibrations. :) :) :) One thing to note is that when you first start the engine, there is a small short thump, that comes from the engine mount. It's not a big deal just something I thought I would mention. Someone else also described noise this in another thread after putting in a high performance engine mount.
There is no reason now for me to buy the AWR mount, at least I can't think of any. For $4 this is a great mod. I believe you could do this on the Mazda 3 as well.

STEP BY STEP:
0. remove mount from car
1. first tape the bottom of the mount completely with duck tape.
2. put mount on flat surface on a piece of cardboard
3.find a small container to mix it up in (a lid from a can of spray paint works great), squirt it all in and mix well.
4. pour the mixed epoxy in immediately after it is mixed (you have a few minutes before it starts to setup)
5. fill the mount all the way up with the epoxy
6. keep the epoxy out of where the bolt goes !
7. wait until very hard (about 3 hours)
8. remove tape
9. remount the mount in your car
10. tightened all bolts nice and tight
11. drive car - enjoy

One other thought: For those of you who think the epoxy wont give enough, the stock rear engine mount has enough rubber all the way around the center bolt that there is enough "give" to allow some movement of the mount. Also the stock rubber is softer than the urethane high performance mount, the epoxy just cements the whole thing together and gets rid of that pesky air gap in the mount.

i read on another thread that there might be a recall on the motor mounts and that they will swap out the 3's mounts and put the 6's mounts on since i guess they are bigger.

very interesting, as i think mine may have a problem

[II-Savy]

Any thought to using a silcone / outside caulk you could use? It woul dkeep the rubber feel and still fill it up.

Doubt if it would hold up very long. The epoxy I used is 1900 psi - pretty tuff stuff. Anyhow I'm real happy with it, it feels great.

[protegeV]

I've seen a lot of people use this technique on other cars with semi-solid mounts and it seems to work very well overall. Good job

[RevLimitLaunch]

best thing is 3m windshield urethane. pick up a 12 or 16 oz tube (cant remember) for 10 bucks at autozone. i used it on to fill all my mounts on my 93 talon and it works more than perfect. got rid of a lot of problems since my mounts went to shit but i didnt have money for the energy suspension mounts. 20 bucks total and an afternoon and my car feal crisp after. the epoxy is a good idea too. but for an alternative i believe the urethane may have a little play in it but will definitley hold up no problem. it did on mine for a year.

I asked the dealership about the recall and of course they know nothing yet. I'll keep asking.

[bbrich57]

I believe what you are all referring to as a recall is actually one of two TSB's issued about the third engine mount. First issued 7/13/05 and titled Engine Vibration / No. 3 Engine Mount Rubber Broken. http://www.finishlineperformance.com/mazda3/docs/0030.pdf
The second was issued 7/21/06 and is titled Body Vibration at Cruise Speed.
http://www.finishlineperformance.com/mazda3/docs/0049.pdf
According to my research, there are currently no recalls or TSB's specifically concerning the MS3. There was ever only one recall on the 3 series and it was for '04 models and concerned the front crash sensor.

[benzo]

Okidoki, I just performed the mod. I used super glue's plastic epoxy. It dried super fast and worked awesome. I do have that slight thump when you first start the car. I can totally tell the difference. I hope to hell that the fill in works for a long time. The mod is super easy to do, and the throttle response is instantanious.

[knowledge007]

I just installed my AWR 88 and it feels great... although the car does shake during the first mili seconds of launch but eveything is great. You feel the car's engine really sturdy. Almost all wheel hop is gone. I don't remember the thread that was asking about my mount but their it is. I might, im not sure, but i might call AWR and get the 70 durometer instead, but for now I am going to try it out for the w/e.

OUCH!!! You installed the 88... for the STREET?? I say again, OUCH!! That one is meant more for drag racing than for a street car.
My 70 is buzzy enough. It solved the vib @ speed problem I've had since day one, but now the car vibrates @ idle. It's a bit annoying but I don't plan to change back anytime soon either. As you say, take off is smoother and more positive.
Besides, I kinda' like the car being a little less civilized. (laugh)

For those that haven't seen/don't know the differences I took a picture...

[elderlycoffee]

this voids the warranty if they find out rihgt?

[clos561]

this voids the warranty if they find out rihgt?
no

[jweidler_1130]

Any manufacturer that wants to void the warrenty for any after-market work that you have done to the car has to prove (legally) that the after-market work caused the issue that you are having. For example, if you install an after-market CAI (cold air intake) and then you have problems with your electric window motor, they are totally unrelated and this would not affect your warrenty for a defective window motor.

However, if you installed a CAI (for example) and you did it incorrectly and there was damage to the engine due to dust particles and debrie getting in the engine, then you may have screwed yourself.

However, with installing your own engine mounts you need to be careful. If there is damage to the engine due to an after-market engine mount failure that causes your engine to fall or tweak, then you might be in for a battle with the dealership.

Question: I don't have an MS3 yet, but am seriously considering purchasing one in July '07. Would you let this issue affect your decision to buy the car? Is there anything I can ask the dealer to do prior to owning the car?

It sounds like there is really no TSB out, which would require the dealer to fix the engine mounts prior to them failing on you.

[SPEED305]

what does the number stand for? 80? 88? 70? thanks

[Yamaha72]

The numbers are the durometer ratings, the higher the number the stiffer it is.

[bbrich57]

Yeah. This is only my opinion based on what I know, but for reference I'd have to guess that the stock mount, w/it's large rubber bushing and it's air gaps, would rate somewhere between 50-55 durometers. That's my impression after doing the mount.
The 70 is quite a bit stiffer than stock, and I can only imagine what the 88 must feel like. I wouldn't do that one unless I were drag racing the car.

[dichiee]

noob question... where is the rear engine mount exactly located?

[bbrich57]

noob question... where is the rear engine mount exactly located?

On the 3 series, it's nearly directly under the drivers right foot. The rear of front subframe. If you raise the car up enough to do an oil change, you will see it if you look.

[Falconx84]

Can you do this mount w/o removing the motor mount?

I just saw the "$4 - tighten the shifter" thread and figured I'd do both of them together since the car won't move for several hrs

[laloosh]

no you cant. The mount is easy to remove. 4 bolts and its out without shoving the engine out of the way. You also do not need to support the engine

[jheer]

It's all a matter of opinion. I did this mod for all of the engine mounts on my Sentra SE-R, and I used 90 shore urethane. It made the car sound meaner and better. Some went even stiffer than that.

Given that this car is a little more "civilized," it might be better to go with 80, but don't be afraid of 90. There is enough rubber in the mounts to give plenty of cushion.

[CaSHMeRe]

Wow. How harsh is it while driving? How about at idle?

hard to explain but i will try:
actually not bad at all. the problem with tough poly is that the force of the engine moving makes longer waves in the car and are more spread out/noticeable. the aluminum makes these waves a little more distinct and really really fast. so, its actually smoother.

hope that makes sense...lol...

The only negative I experienced with the harder urethane was the buzzing of interior plastic parts, especially in the cold at idle. Does the aluminum bushing cause that kind of buzzing?

[CaSHMeRe]

nope, no weird buzzing or sounds...however, on WOT, you can almost go def !!!!!

[sl0wthe0ry]

Just got it done on my 05 M3.
Couldn't be happier.

The M3 does have more space to fill in than the MS3 mounts, I had to go back to Lowes to buy a second epoxy, but much much better. Not as much vibration as my friends MSP with the AWR mount and still does the job.

Thanks for the help and info guys.

[drledford93]

I really want to try this, but I can't see the pics from the original post! What's up with that?

Daniel

[drledford93]

Wow! Now I can rotate (ie/ slide) the car by off-throttle oversteer! The car is sooooo much more responsive now that I've stiffened the mount. This mod is so easy, I don't see why anyone wouldn't do it. Why pay $100 when you can pay $4? (naughty)

Daniel

[Falconx84]

actually.... the equivalent of filling the mount is the corksport inserts which run about 30

not tight enough with epoxy

off throttle oversteer..... the idea of this epoxy mount is that it helps stiffen the mount under load. Off throttle you're not under load so there should be no difference. Unless modding the mount happened to coincide with you learning the car a little better

[drledford93]

Possibly, but the engine's recoil was faster, thus being more responsive and causing off-throttle oversteer faster. I have tried for a while to do it, but the engine is (was) too similar to my wife's Focus ZX3, which takes a year or two to recoil...(protest) It did stop the majority of wheel-hop and is not too harsh. At any rate, it does snap my head back now!(shocked)

I thought about the inserts, but shipping was $10 from the place that had 'em (can't remember where I saw it, but it threw me off...)

Daniel

[Falconx84]

su.... s-t-r-e-e-t u-n-i-t has free shipping as well as protege garage, for when you decide to go with a different mount. I say when because you know if it feels this good now, how much better will it feel with a diff mount, lol

I'm getting the trz dogbone, but I've heard good things about the su mount, just so you know....

[MS38449]

Damn I wish I would of seen this before I took my battery out to get to the O2, I guess I'll just wait to hook my test pipe up until I get the epoxy for the mount and do it all @ once. Kudos on the repost(yippy)(boobs2)

[drledford93]

I'm old enough now to know where the fine line between discomfort and performance is...(hand)

Forgive me for raising the dead here, but I saw the 'stiffen your shifter' thread and came here figuring I'd do them both!

Will I need to lift the car up to get this done? My dad has a heavy duty car jack that we've used before, but if I can get to the motor mount without doing so that would be awesome. Or are there pics someone can provide?

Is everyone still enjoying the effects of the mod? Everything going smooth?

Many thanks!

Hey I was just gonna ask you how your mount was holding up.....and you answered before I could even say anthing....I'm gonna give it a shot....thanks....oh and I know someone asked this already, but i think it was for a non speed3 vehicle.....but where can I find this mount? sorry, I'm a noob still...

its pretty easy to spot. Get your car on jack stands, and you should be able to see it. It's actually a tranny mount. It looks the same as it does on the pictures.

damn thanks man! im gonna go try this asap!!!

k im in the process of finishing. its now drying up and for now till its dry im riding with a MS3 motor mount on! its better that the M3S but hopefully the epoxy gel will make it way better!

completly wasted one epoxy glue bc i didnt cover the buttom part (hand)

but put some tape on the buttom and got it ready to go.
cant wait to try it on. which prob wont be till Wednesday afternoon... (i got class tonight and work all day tomorrow..)

my opinion..... its a waste of time, go ahead an cough up $100 for a mount and forget about it. Or go with the corksport inserts for like $35

(iagree)
same here jut felt like trying it out. im usually dont try stuff like this out but u could say i was bored lol plus i dnt feel like spendin 100 bucks right now.. for now im just goin to kep using the Speed3 motor mount i have on which seems to be doin the job!

if anyone has "how to" pictures of the process please! post em!!!

but for know i have wasted my time and money bc that shit spilled all out through the buttom (yes i had it covered) but the glue is too thick n heavy..(braindead

[Ghetto Mods]

Worked fine for me on a speed 3 mount. Were you trying to do this on a standard 3 mount?

For the spillage just use a couple layers of tape and set the thing on a piece of cardboard - you'll still have to peel that off, but whatever.

As for a $100- mount, I'd rather spend the money elsewhere, so I'm all about doing a cheap mod myself if I can. And I'd bet money my epoxy mount is hella stiffer than the corksport inserts.

i did use tape! what tape did u use?
and how long did it take to dry? did u do all the glue at one time or id u put it in layers so it would dry faster?

Epoxy does not "dry". It cures in a 2 part chemical reaction. Thickness does not change the cure time. The correct ratio and thorough mixing are very important. Do not try to mix it in the mount.

k so excuse me if i sound retarted lol but wat ur tryin to say is to mix it first??? or just to squeeze the gel into the mount and let it sit tthere?

what i did was exactly like this..
took the motormount off... taped the buttom part with clear thick paking tape... squezed the 2 bottles of epoxy gel inside and i let it sit for the longest time.. then when it sarted dripping out after an hour or two i tried taping it more and it kept dripping out. i left it alone and still havent looked at it... who know if it dried up or not...

Yes, you must thoroughly mix the epoxy first before putting it in the mount. I suspected this might be the problem from your description. You might as well get some acetone or methylene chloride and try to clean the mount up because it will never cure as is. Your not retarded, just at the low end of the learning curve for this particular process. Everyone makes mistakes while learning. One of my suppliers was making a fixture to hold a passenger airbag cover. His mold failed and he dumped 3 gallons of mixed 94A urethane on the floor. That's $180 per gallon......and a helluva mess!

From the 1st post:
"I put tape on the back side of the mount to contain the epoxy. I mixed the entire tube of epoxy and poured it into the mount. 1 tube of this is all you need. It flows just right and entirely filled the gap. In about 3 hours it is rock hard (let it setup in a heated area)."

Sorry you didn't read before you squirted un-mixed epoxy into your mount.
I did this 15 months ago and it's still holding up fine. I would suggest you follow enganear's advise, and spend $4 more bucks you will be happy with the end result !

damn well thats good to know now! i still have one left so i guess that saves me a trip to HD (alright) i wish i would had read lol but its part of learning! now my mount looks like crap i have it soaked in hot water tryin to get it off. im going to try chloride see how that goes! i appreciate you help guys!!! (drinks) tomorrow im goin to try it again! wish me luck lol

k btw so just to get it staight! mix well!?.. is it supposed to get thick? and mix it like on a piece of cardbox? put tape on the buttom!? and pour it in!?

if that;s perfect then im goin to do tomorrow after class!

nite.

[flyrevs]

OK,
1. first tape the bottom of the mount completely with duck tape.
2. put mount on flat surface on a piece of cardboard
3.find a small container to mix it up in (a lid from a can of spray paint works great), squirt it all in and mix well.
4. pour the mixed epoxy in immediately after it is mixed (you have a few minutes before it starts to setup)
5. fill the mount all the way up with the epoxy
6. keep the epoxy out of where the bolt goes !
7. wait until very hard (about 3 hours)
8. remove tape
9. remount the mount in your car
10. tightened all bolts nice and tight
11. drive car - enjoy

you have to mix the two bottles together before you put it in the mount.

i'm doing this mod right now but to help speed the process along i'm baking the mount at 150 so the heat should help cure the epoxy faster.

[detsilverms3]

totally worked out. eliminated most of the wheel hop that was there not all of it but most of it. pretty happy with it. i ended up need two packages of epoxy so it cost me 10 bucks but for ten bucks you cant complain, you know?

I also noticed while driving it last night and today that the car just drives a lot smoother now. There is still some hop when you get on it but it's no where near as bad. (btw i used this epoxy that was rated at 2600 lbs. i saw it and figured hmm...might as well.)

[vimo19]

Do you get any vibrations at idle ?

[Kynetx]

Anyone every try a polyeurothane adhesive like Gorilla Glue?

[enganear]

Gorilla glue is good for thin films only, and I don't like it much even for that.

Amazing stuff for woodworking, as long as it is in an inconspicuous area.
The expansion effect is both a blessing and a curse.

[trufanatic]

i'll be trying this, probably the most worth while how to yet.. Thanks

[FrancoNemo]

k so finally i got time to install it!
that shit is the best!
idk what i did different but my def. does vibrate! it feels like a speed with a motor mount! my engine is so stiff idk if its safe lol rides soo much better no more wheel hop at all!!! LOVE THE MOD the best HOW-TO ever!!!!!!!!
BTW... i painted it red (i was a lil bored and figured i'd make it look different!

no vibes at idle. at first i don't know what happened maybe just a resettling, but i got a bit of a pop first start and first couple of passes. but everything is holding and like i said it rides smoother and has way less wheel hop. i love it. cheap and effective.

I've used 3500psi high strength yellow transparent stuff from Pepboys. it's rock hard. is it supposed to be this way or should it give in a little? never worked with epoxy before so don't know whether the end products of 1900 and 3500psi are somewhat the same. thanks for your help.

[fructus]

Thank you.
Put the stock/epoxy mount back in today in place of TRZ Poly. What a relief from the harshness of this mount!
I'll see tomorrow how big is the performance difference.
As I was torquing the vertical bolt the epoxy on the bottom part cracked in one spot. I hope the crack wasn't deep. And how does it crack, anyway? The stuff is supposed to withstand high amounts of pressure. The only reasonable explanation comes to mind is that it cracked in the spot where the surface of epoxy was uneven due to the fact that it took the shape of the tape covering the bottom of the mount as I was pouring the epoxy in.
I'll be checking it every now and then to see how it holds up.
Maybe will upgrade to the Street Unit mount.

Maybe will upgrade to the Street Unit mount. the cracks are only in the areas of the epoxy near the edge where it is real thin - I've had mine in for 16 months now and it's holding up fine.

[samsel450r]

i put the derlin dog bone motor mount and it made my car feel like a piece of junk.... at idle it would vibrate the whole car and when you would tap the gas it would vibrate even harder... and i didnt think going to a stronger motor mount would make all the tranny noises so loud all you would hear when you would drive is transmission noise and loud vibration... and after about 6k miles i hear this raddling coming from undernieth the car on ever bump it sounded like a bold was stuck somewhere and was just jumping around... so when i put the stock mount on all the noises and vibrations went away and i was happy again.. lol... but i hate the wheel hop i got now...and not to mention that the rubber on the stock mount is all torn up...so i cant launch it untill i get a new mount..

[eddelgado]

I just want to make sure that you guys all know that CorkSport makes a two piece Urethane insert that does the same thing. It sells for $35 you can get it in black or blue. If you need to remove it because you think the dealer may have an issue with it you just unbolt the mount and pull it back out again.

I put it in my MS3 about a month ago.

Ed.

[jasonl33w]

Maybe this is a dumb question, but is there any point in doing this to the other engine mounts as well? or is the design different in that there is not the same air gap? I have not looked, just wondering if anybody has done that.

[CWPspeed3]

I've been looking at the cork sport inserts as well but I also have some industrial epoxy at 4,000 psi strength. Cost aside are there any advantages/ disadvantages to using one over the other?

I think the inserts are a much better way to go, if u can fork over the extra 20$ or so over epoxy. For one, if you don't like the feel of it, you can pull the inserts out and return to stock in minutes, with epoxy it would be much harder if not impossible to return to stock. With the inserts you don't really have to worry about any cracking or breaking down of the material, the poly is probably more resistant to the weather, heat, chemicals, etc also. Just my opinion, I'm in no way an expert on the situation though.

[flyrevs]

when I first did the epoxy mod, there were no inserts. Now that there are, the inserts are maybe a better alternative for the reasons stated by 5][Spyder, (iagree) plus they are not that much money. If my epoxy ever breaks down I'll be tryin the corksports. Has anybody with the epoxy mod ever tried the corksports ?

I still think the epoxy mod is a good one and definitely worth doing, just that the inserts now make a bit more sense.
Thanks

[CWPspeed3]

Where do you guys order your corksports inserts from?

[MikeHTally]

Guess I have to ask a stupid question: Once the two bolts are out, how the heck do you get the mount out? It won't slide back, and I don't see a way to slide it forward enough. Also, is the engine supposed to shift rearward enough to make it a B*TCH to just put the mount back in?

[bbrich57]

It's actually quite easy to shift the engine/trans forward by just pushing it with your hands. When you do this there is just enough room to remove/install the mount.

[MikeHTally]

Oh, OK. Thanks. It was still a trifle warm when I touched it with my hand. I knew I wouldn't be able to hold that and still be able to work next week.

[MS38449]

DDD, that's why they make Mechanic gloves or towls. ;)(rockon) Dude!

[b-ron]

i cant get the bolts loose, do you guys use air tools or just a breaker bar thanks

[bbrich57]

1/2" drive ratchet/socket should do the trick. The spec is only +/-65 ft.lbs.

[MikeHTally]

Got 'er done tonight. The LocTite didn't settle into the void as I expected, so I went to Wally-World and got a $2 tube of 1500psi epoxy to fill in from the other side. Got the mount put back in about ten minutes ago. Pushed her off the ramp, 'cause the second epoxy had only set about ninety minutes. I'll start 'er up in the morning an' see if I can tell the difference. I may do the "free" shifter bushing tighten tomorrow.

FOLLOW UP:
I'm getting a vibration at warm idle. Not severe, but very noticeable. I've always been very cognizant of squeaks, rattles, shakes in my cars and I try to reduce/eliminate them if possible. If I rev it up even a little bit, it smoothes out. Is there a way to raise the idle just a bit?

The throttle response seems better, but that may be me getting used to a stick after twenty years. At a kilomile, the drive train is probably loosening up, as well. This car is as much fun to drive as I'd hoped it would be.

[sebspeed3]

so i did this today and i had to drive it about 2 hours after and i was impressed on the difference and i just dropped off my lady and its cured for about 6 hours already and holy shit. its so clean and crisp now. i wouldnt spend the money for the upgraded bushings

[danmowchan]

Well, I've been looking for a while and I have no idea where this thing is located..

Can anybody show me some pictures or maybe some more guidance? Thanks.

[bbrich57]

It's the rear mount behind the engine/trans and ahead of the cat converter.

Thanks for replying so fast =)

I'm at work now so I can't give it a look. But, tomorrow morning I will probably jack it up again and take a look. Should I jack up the front or the side?

get jack stands
and read the multitude of posts

[southendskin210]

so what about the passenger side mount that shit is horrible can we fill that in as well or its just the rear mount man ive been meaning to do this just did the struts and springs but couldnt fit the mounts into my day......sooo fomaco sucks!!! i think thats our mount brand......(flame2)

[bbrich57]

I think you mean, FoMoCo, there soldier!

SAY! OPEN YOUR EYES! If you don't see it under the hood? Then more than likely, it's under the car.

Just a hint from a shade tree mechanic.

Hell I hope you know what it looks like with all the post scenes the MS3 has been out.

[southendskin210]

so all mounts or just the rear?

[Gibson486]

I am guessing that this is really only for stick versions of the 3?

[cymx5]

Just did this today. Wonderful improvement with zero extra vibrations.

No more ratcheting sound from the transmission during hard shifts or downshifts. $4.99 + tax though, not $4 (stripper).
