A couple of thoughts here. In talking with Jim Bell (Kenne Bell Perf.
Products), he said that they were having problems with the intake manifold
plate gasket. They have a special gasket that they include with their
supercharger kits to correct the problem. He even indicated that he has seen
many manifolds leak on stock motors. If the plate gasket were to leak, there
would be soot in the intake track but every engine I have worked on with a
dry intake system has the black soot. Every used TB that we have pulled
apart is the same way, especially the IAC passages, so I don't think it is
unusual. If you are going to remove your manifold, check the gasket and you
might give Jim @ Kenne Bell a call. I am sure he can provide some
assistance.....
