Trying something new for motor mounts
 

So I've seen the recipe for 3M Window Weld urethane mounts. But that stuff ain't cheap. So, I went to Home Depot and picked up some PL Premium Construction Adhesive for $2.97 for a 10oz. cartridge.

Now for some pics.

You can see the cracks around the perimeter.

I stuck the nozzle in the cracks and squeezed (did the same thing last night ;)). Just waiting for it to dry....

WTF? At least you could have cleaned it up a bit. :-X Let us know how it works out, and be honest if it sucks. :P

Too hard to do anything when it's all pastey. Just gotta wait a few....

Re:Trying something new for motor mounts
 

I use that stuff all the time. It will just crack apart and fall out.

Re:Trying something new for motor mounts
 

Ahh ---- it. I just slapped that bitch back in and went for a nice long drive. Gonna get some 3M Scotchcast 226 Polyurethane resin. ---- turns to rubber...

Go to http://www.mcmaster.com and search for item #8644K11.

It's 80a durometer urethane. Works great.

;D

Re:Trying something new for motor mounts
 

just use the mount helpers . those lil pads that come with the stock mounts that u put on the sides when u bolt it up to the frame. that ---- will never fall out. thus keeping it in one piece. be honest if it works well. dont tell us its good if that ---- falls out.

Re:Trying something new for motor mounts
 

I can't see that ---- being any good, it shrinks too much to make the mounts stiff, you would have to put it in let it dry, over and over again, and even then it would be too brittle!!!

Re:Trying something new for motor mounts
 

Well, couple of you wanted an update.

Like I said, I got tired of waiting (picked a bad time to do it) so I put it back in with half-cured polyurethane. Shortly thereafter, I went for a spirited drive. I came home, popped the hood and quite a bit of oozed out.

Over the course of a few days it finally cured. It's hard, but still somewhat flexible. I wanna say it's like Shore 80a. Either way, still a hell of a lot better than a torn mount. Think I might take it out and make it look nice (function first...then fashion).

Just get silicone caulk and fill it up? Thats what I did. I bought motor mount inserts, but ended up tossing them and just filling the mounts up, it definitely makes the car a little more stiff (you can feel the engine vibrations a little more) but its still lasting about 10,000 miles later. I probably need to redo them when I do this next swap, but we'll see.

Man I love Google!!

Just did a little searching and found this gem:

http://catalogs.google.com/catalogs?...31&catpage=975

Notice the Flexane 94... $30 for a 1lb container. Though, I'm not sure how much 1lb will do. Either way, exactly what I needed!

Re:Trying something new for motor mounts
 

just buy the $9.99 windo weld urethane glue when it dries its just like rubber

Re:Trying something new for motor mounts
 

where do u get this window weld, i cant find it anywhere. i went to napa and found some red polyurethane glue type ----, will this work.

Re:Trying something new for motor mounts
 

napa should; have but its black;and don't get that ---- on you it wont come off ;)

Re:Trying something new for motor mounts
 

3M window weld is what it's called. I've filled three of my mounts and will fill the fourth once the motor is completely out. Should be a nice teeth rattling ride when I'm done. ;D

Re:Trying something new for motor mounts
 

I did the window weld and the motor mount insert (at different times).

They both make a HUGE difference, but I prefer the inserts... For some reason there's less rattle.

Re:Trying something new for motor mounts
 

the 3M window weld is stiffer ;D

Re:Trying something new for motor mounts
 

The rattle is just the result of the cabin feeling all the engines vibrations instead of it all being dampened out. So the more chatter you hear, the better I would assume :)

Re:Trying something new for motor mounts
 

I got the shitty end of the deal on mounts. the side ones are stiff as ---- so the car rattles like a mofo, the front mount isn't there, and the back one is the crappy stock one so I get lots of engine movement and a rattly car.

Re:Trying something new for motor mounts
 

hrm... I'm just thinking that my rattling is generally the stuff inside the cabin shaking (for instance, I have my license plate in the window rather then on the front bumper). You can definitely feel the engines vibrations more, its a good ass massage.

Re:Trying something new for motor mounts
 

I should have mentioned that I only did the lower side mounts with 3M and did all 3 (sides and rear) with the inserts. I haven't been to the track yet, so I don't know how much of s difference there will be in 1/4 mile times, but I like less rattle on a daily driver. The inserts might be a good in-between from totally hard filler (3M) and nothing at all.

Re:Trying something new for motor mounts
 

I suggest getting inserts along with window weld. I tried using just the window weld and I got it everywhere, but the motor mount (kept leaking out). :(
