That's the insane part about the price. It's not a fluid filled mount. Apparently the manual transmission car is sort of a unicorn when it comes to a few of the motor mounts.

I plan to try this with the easy to get to mounts first, and if it works, I'll invest the time in more difficult to reach mounts.

Some companies make urethane inserts to fill the holes in the OEM mount, I wonder if putting in an insert and then drill holes into it to soften it until you like it, would work?

will be interesting to see how they hold up. Not sure if you did much to ensure bonding to the other parts (granted you used adhesives), and if it is the right stuff for the heat and everything else.

Still, nice job! I hope they last and keep us posted. OE stuff cannot be THAT different, other than how they pour/craft and cure the materials...

Here is my attempt for the Protégé 5

https://www.dropbox.com/sh/7j6qt4nb7x8y4zl/AACkbXZ_-ohOQ5UVmpMor48ha

I supported the engine, removed the mount. You can see the mount is completely torn. I cleaned it with brake parts cleaner and then filled it with the 3M windshield urethane. It is supposed to be fast setting. From what I've read, 48 hours should be enough. I am giving it over 72 hours while I am on a long weekend with oilBabe.

For some reason, a good quality mount for a manual transmission P5 is $150-200. So $18 in urethane and 90 minutes time is a worthy gamble to see if this works.

The other mounts are more realistically priced so if needed, I will buy replacements.

Of course, there are other "synthetic rubber" options that cure rather rapidly. No need to wait 4 months!

I've done similar things with engine mounts, transmission mounts, suspension bushings and yes, even pneumatic tires.

1) Polysulfide rubber sealants (for aircraft fuel tanks and for sealing the fuselage) such as PRC-Desoto PR-1422 (B2 cures in 2 hours, B-1/2 cures in 1/2 hour)


2) 2 part polyurethane of nearly any durometer you want (softness) I typically use 30 durometer. This stuff is cheap, easy to mix, easy to mold (such as in a paper cup) , makes great suspension bushings and so on. The pic says "RTV" which means "room temperature vulcanizing". It does not mean it's silicone sealant.

Another quick note:

The 30 durometer poly is great for various applications. One use is to fill small Chinese tires so they don't leak down overnight. Another good use is to re-fill leaking "liquid filled" engine mounts and suspension bushings. Just mix up a batch and inject it in the empty mount/bushing using the holes you drill. Works like a champ.
