Filling worn motor mounts

[RYS13]

What do you guys recommend using to fill up worn motor mounts? Would a rubber-based sealant work? Thanks.

3m polyurethane window weld

yeah and you don't really fill them. you slather it all over them.

is that ayanami rei in your avatar?

[RYS13]

Yes it is. And thanks for your help.

rei is a very confusing character....evangelion is confusing altogether (maybe someone should start an Eva thread...)

anyway i remember reading somewhere that motor mount repairing supplies:o can be bought at home depot....

This topic has been covered many times. Most caulk-type sealent should work. But a lot of people tend to use 3M window weld, because of it's stiffness. There are others that are stiffer, you'd just have to do your own research on them.

I just use bathroom sealent, and it works great. No major engine vibration, nor do I feel it in the cabin either.

Here is the end result:

got tired of the clunk flop clunk wheni start my car. just ordered new mounts from performance nissan. So, i won't be going that route. I know it's been done using the polyurethane caulk.

Better off drilling a hole in the side of the mount. In the center of the rubber section.
1)drill the accordion section.
2)drain all the diarrhea looking fluid.
3)heat Window Weld to 170*F
4)inject into mount.

some of that industrial urethane designed to fill in concrete is the great stuff.

s14db method of filling in the mount is a very good idea.

If not search some more.

just break down and buy some Syko Performance Custom Polyurethane mounts from me. They are a hundred better than trying to do it yourself with industrial window poly that was not designed for what your trying to use it for.
shameless self promotion here :D

I used black urethane caulking on my civic, worked wonders. I've been considering either doing the same to my 240 or welding them solid.

I used the same window caulk as V did. My motor barely moves when I start it. Hardly shakes when I rev it. I couldn't be happier. Only cost me $14 too. You should get a spare set of mounts though. . .because the caulk takes a week to cure, and harden.
