Motor Mount Insulation
Friday night in preparation for the run up to the Petit Lemans I decided to replace my starter. I did not want the old girl to fail in front of all those shining C5's and C6's. While up under the car I decided clean up some things that hung too close to my headers!
I noted that the insulation around the motor mounts was too close to the headers. The headers were once uncoated and I have since had them Jet-Hot coated. The insulation was burnt from contact with the previously uncoated headers. The damaged insulation made contact with the headers. The look of it scared me. I removed the insulation. I understand that the mounts are oil filled. So here is the question... Did I open a can of worms? Has anyone else done this? Will they last like this?
PS: I will begin my search for solid mounts soon... I believe NitrousSam had a batch made awhile back. Anyone have a update on them?

Since you have a '94, the motor mounts are indeed oil-filled. The insulation keeps them from wearing out prematurely.
Unfortunately Sam's mounts were the earlier design. I actually bought a set and later realized they wouldn't work. He was talking about coming up with ones that will work on LT1/4 cars, but I don't think that's happened yet. The good thing is the design for a solid mount would be pretty straightforward.
Unless you totally trashed the insulation taking it off, I'd just re-wrap it and tie it up with stainless wire.

Ive had headers and just recently ditched my insulators. I think it looks alot cleaner now. I don't think you need the insulators with headers as I believe they are there because of the cats that are normally near by. The cats get alot hotter than the headers. Just my opinion!

Bringing this thread back. I agree you dont need the inulation. There are plastics near headers that last, ie Brake Booster.
Mine is tore up pretty good. I may use a header wrap, and steel wire it down.
At least it will look cleaner.
