I am running a eldebrock street tunnel ram and have a vacume leak where the top half mates to the bottom half, is this a common problem? I was thinking about putting silicone between them instead of the gasket but am not sure what type I can use with gas.
I'd just get a new gasket. They can't cost more than a few dollars, possibly cheaper than the tube of good gasket maker.
No gasket just ultra grey silicone works for me, only problem is you'll need a pry bar to get it apart again.
