i didnt wanna start a new topic for this but i did a quick search and only came up with basic info.. i no what i need to use to fill them..but ..can i fell them in place?...i can take my sides off and front fairly easy if i recall but the back is a pain in the a-- and usually comes out with the engine ... can they be done in place.if i hoist the engine and fill the ones with no streess then adjust accordingly

They cant be done in place, take them out to do it as the stuff is liquid

So what does everyone recomend to fill the mounts with?

Poly Liquid... I think it's Grade A4... search that.

80A

Thanks... Yes it's 80A. That's what I used!
You'll hate the vibration, but the feel is awesome.

If you absolutely don't want to take them off.... I thought of shimming mine... You could make hard rubber inserts, and shove them in, and then bolt plates onto each side to sandwich them in. The plates would also act as stops, to keep the engine from moving past a designated point, as long as you have at least 5 bolts around them (More, if possible). I haven't looked into exactly how much room there is between the 2 metal parts of the mounts, though, to see how feasible it all is.

that seems so intence lol. .. i think ill just see what it looks like.. i jsut no for sure that the back one is a pain in the a-- to get off..

You can support/raise the engine with a jack under the oil pan and do the same on the trans then both the rear and front could be removed. Spray the bolts/nust with penatrant first. I used Devcon Durathane 94. It's a two part and there's no doubt your mounts will be stiffer and stronger. $50 a pint will do 2 cars. This product can totally replace the rubber in your existing mounts as well. It's meant for rebuilding rubber components that are no longer available.

Where can you buy this stuff? Ive been looking around locally and have only found some polyurethane in caulking tubes at lowes. Any word on how strong it might be if used in some mounts?

Just an idea...People have used hockey pucks.

And when you fill them, do them in 2 steps....do it all at once and it's too much, they don't cure properly.

I used window weld

I got some 95a urethane from a place in Canada called Acklands-Grainger they have some 1lb liquid poly urethane (flexthane) kits there for about 65$
