Window weld motor mounts (poor man's solid mounts)
Has anyone ever tried this?
![]() I know, it looks ghetto. But people have done it and it's held up for years. People report it being easier, and cheaper to put in than motor mount inserts. I don't want extra NVH though, so I dunno if this is for me. But might be worth trying for less than $15. Ideally, I would get the JDM STI mounts for the engine and tranny. But that's $700 that I'm not ready to drop quite yet. thread I referenced: http://honda-tech.com/showthread.php?t=672359 |

Are there any voids in the factory mounts?
Yeah, I've done it before. It will add NVH, or it did on the car I did it on. Make sure you put in a layer & let it dry, then do the next layer and let it dry. Repeat until you have the voids filled in. Otherwise the center will never dry. |

I did this once in a pinch when I broke a passenger side motor mount on an RSX and there was a national backorder and could not get a replacement. The motor mount dropped on the frame, and it was fluid filled but ruptured.
It worked for the week I was going to leave it on, so I drove it for another 3 years before it got stolen lol It does work, but I wouldn't go making a motor mount from scratch when there are aftermarket alternatives available

Yeah, but, new motor mounts are a LOT of money. If I can smear this stuff into my new engine mounts to stiffen things up for a few bucks, with no drawbacks, I may just try this.

If my car is ever done I might try and pack the tranny mount. Just because. Not like its any cheaper then a whiteline mount though. Ive done it before on cars that didnt have aftermarket mounts.

I have an STI trans mount and waiting on engine mounts before I install it all at once and I have to say......this is not nearly as dumb or "ghetto" as I had expected...
Do it. Post up results.

Some people get pretty ghetto with it but honestly if you have a mount that has empty space in it and all you're doing is packing the empty space than its a viable alternative to expensive mounts for a street car

My fear is that a solid mount will transmit too much NVH. But for someone who likes to experiment, why not? You might get what you're looking for and save hundreds in the process. |
