I have a B7 S4 with the 4.2. When I took the intake manifold apart to get the top part powdercoated, the rubber seal inside wasn't cooperating. I cleaned off the rubber and gasket material and used my own silicone gasket maker. I don't seem to have any vacuum leaks or anything, but I was wondering if I am the only one who has run into this? Is there a better method of assembly?
