i have heard some people fill their motor mounts with something, so first off what does that help and what do they use? is it worth while? just wonderin thanks

 

I think with some type of a silicone to stiffen the mounts, it will help reduce wheel hop

 

In last months Sport Compact Car Mag they filled the Project RSX s's motor mounts with polyurithane by taping off the on back side and pouring it in from the other. It is done to stiffen the motor mounts for less engine movement under a load and I figure it would be worth while if you already had the engine out.

 

Use duct tape and tape one side off. Buy some stuff at Advanced Auto called "Window Weld"......it is to re-do the seals around your windsheild. Fill the mount but have a tiny little long toothpick or if you are willing to sacrifice a old screw driver keep stabbing it kinda to force all the air bubbles out of it. After that either put it in a oven for about 12 hours on bake around 200 on the temps or let them siit in a dry place for about a week.

 

Dang, 12 hours in the oven! That will hurt someones electric or gas bill. But it is still better than paying for aftermarket solid/poly motormounts.
