I put on a S2 I/C from ZZP. There is a passage for the PVC valve cut into the ported LIM. If I got that clogged with sealer obviously the PVC system would not work as intended. Could that cause a rise in internal pressure? I replaced the valve cover gaskets last year when I did rockers. After the I/C install I am getting a little oil seepage from under the Valve cover gaskets. Could that be related?
