Stiffining Lanos engine mounts

MMamdouh · Post by **MMamdouh** » Mon Apr 17, 2006 8:45 am

hi guys... i thing i have distroyed my 4 months old engine mounts again (or at least one of them) so i am going to buy a new set but i won't put them on till i stiffen them a little bit to handle the strain.

now i have some quetions about this project:

1- can one use any silicon product to fill the mount? i mean my options are not just black glass silicon... right?
2- does the fillup should be 100% silicon? some people said they used urethane or so.
3- what other material can i use to fill other than urethane? can i use wood and seal it with silicon for more stiff support?
4- how long should i leave the silicon to dry out? some people say up to one day... is that correct?

also any other tips or advice is always welcomed... as always when the priject starts pics will be uploaded ASAP.

thanks for the advice.

I looked into this a little while ago but never did it (i bought huge heavy chrome wheels to offset wheel hop and some torque steer

)

i tried it before, it is messy, it gets everywhere and hell to clean. also make sure you let it cure for at least 24 hours, i'll say 48 if you can. i was impatiant and ya.

I was few minutes ago in Advance Autoparts and they have the 3M Window Weld about $13.99

I will do this mod and see how it works

car abuse

one q?

my engine mount near the timing belt is a hidromount and it is broken

instead of the fluyd it has inside i can fill it with urethane and make it solid right ?

is better than spending $40 in a new one to break it again

most probably hard shifting and lots of it.

You should be more gentel, treat it like a lady

As far as I know it isn't the color of the silicone that changes it's properties. I know there is high temp silicone and low temp silicone. Beyond that I just don't know.

(high temp will handle temps up to about 500 degrees farenheight, low temp will melt at about 250ish)

The urethane cost only $9 and fill all 4 mount.

i guess even if i got the 250f silicon i am still OK... are their any difference in how stiff both types are or are they the same??
