Cheap DIY polyurethane motor mounts
Update, Th PLS40 proved too soft on Its own. While used to fill in gaps on trimmed and cleaned up stock mounts might work, what I did here initially worked loose and is as bad as before.
I know have 3M# MMM 08693 window urethane I got for $11.23 at NAPA. This is not Windo-Weld, but a cheaper and slower curing version.
My motor mounts are really bad, and I am going to poly fill them with 3M window weld or another polyurethane sealer. Are the steel sleeves for the bolt offset or centred?
I have stripped a pair of wrecking yard motor mounts of all original bushing material, and filled them with LOCTITE PL S40 polyurethane window, door & siding at $7.99 each.

Looking at this picture, I believe they are centered in the X plane, but slightly higher in the Y plane. I believe that's how I remember them looking too, as I installed new mounts about 8 months ago now.

I centered mine as bang on as possible, when installing there may have been a little bit of off-set required but the little play in the 3m weld compensated and there was no issue with the install.

ES liquid urethane = $1.74/oz.
3M window weld = $1.48/oz.
I can walk one block and get all the window weld I want.
I don't have to mix two parts and pour a liquid, worrying about how well I sealed the mounts.
I am not saying that 3M is a superior product, I am only saying there is no compelling reason to use ES liquid urethane over 3M window weld.

I forgot that I kept my original mounts. My previous statement is accurate.
While we're on the subject, I'd like to ask a related question.
3 of my old OEM motor mounts were ripped/torn/disintegrated pretty badly...1 of which completely fell out of the mount. Would you guys recommend re-using them as-is and filling them? Or is it a bad idea to use them due to their extremely poor condition and I'd be better off with new OEM mounts or new cheap Ebay mounts and then fill those in order to get the best solid mounts possible?

As long as you can locate the bolt hole (which you can because I know thats not the only mount you have ), I'd just go ahead and fill the old ones, James.
My OEM side mounts filled with 3M windo weld have held up well for the year I've had them installed.

man, i wish i had a garage around here that would redo all my mounts. i know the cross-member one is original, the front center is a cheapo Taiwan made junker, the one oem one i replaced is passenger side, and the trans mount is a aftermarket with like 80,000 on it. i hear clunking some days when accelerating
and i know the rubber is shot in at least 2 of the mounts. not only that, i was kinda waiting until i did the engine rebuild to do them and got my hours cut in december so i'm kinda stuck doing nothing and cringing every time i accelerate.

Looking forward to seeing the results of this endeavor - i need to fix the motor mount on the pass. side of the engine. Thing squeaks if i accelerate from the stop or otherwise make a jerking motion with the car.

1. Send the to Red Lion Racing
2. Fill them with 3M Window Weld
3. Sent them to me for keeps if you want to scrap them....I'll even pay the shipping for them.

I would clean them up and reuse the Wiz! If they're are M/T mounts then you use the ES inserts! If they're A/T mounts you have 3 choices!

Follow up question Cmax03. It's my understanding that the ES mounts are only for the left (radiator) and right (firewall).....so why do you say if M/T? If I'm correct, it doesn't matter if you're M/T or A/T to use the ES mounts.
#16
Here's another thought for you guys filling your mounts....
What about keeping it half streetable and half track? Meaning, filled poly or ES left (radiator) and right (firewall) mounts and OEM front (timing cover) and rear (tranny)mounts? Considering we don't live on the track, maybe this is the best of both worlds?

I have these and they been great.
The whole window weld thing is about as ghetto as it gets next to using reguar caulking and they are offset, I will guarantee you, you will have lining up issues and you have to set them for 24-48 hours, I don't understand why and how people stand by them so hard, when you are only paying like $60 bucks more for ES mounts.

Just thought this might help, but judging from the comments, you guys already know.

Footnote: excluding GLE electronic mounts of course...

Really? I was under the impression 3 out of 4 mounts were the same regardless of transmission and only the tranny mount differed. For clarification, are you saying the diameter of the metal insert in the middle of the rubber isolator is different in size or the whole rubber isolator is bigger (ie bigger metal mount)?

Is it any less ghetto if ES molds it for you, charges you 10X the price of the material and labor, and then you need to install your self anyway.
I say if you pay the premium price for the ES parts good for you, if you cannot then DIY.

I think the sand and rubber glue is a great idea.
Always hearing about leaks and it being messy.
Makes sense the way they describe it.

Went to the wrecking yard in Coos Bay yesterday. I picked up a set of AT motor mounts for $20.00 and am now kicking myself for not getting all of the fog light parts. Car also had a Blose stereo in it.
From what Ive read the AT and MT mounts are interchangeable with the only difference being the bushing outer diameter. I will not be using ES bushings so it won't matter.

The old bushings came out pretty easy. I just cut the bushing shell with a sawzall and then drove a large screwdriver between the bushing shell and the heavier motor mount wall. After that i just knocked the bushing out with a couple swings of the hammer. Its no wonder the mounts fail, they both were fluid filled with a pot metal and plastic insert moded into the rubber. Sorry I did not photo the crap I took out.

In the two stores I checked, yes. I figured no one was going to be looking under my car anyway.
My next step is to make a couple jigs to locate the the center sleeves and then fill and wait.

Yea....Ill be really curious how that holds up. That stuff isnt meant for weight. Its hardy as I use it on a rental property but as far as holding up under these conditions. Ill be curious for sure. Think I would have used as little as possible like what chris did. Those are the side mounts correct?
