The plastic inlet manifold gaskets are a common problem with the ecotec motor. The plastic will distort and crack over time causing coolant leaks, oil leaks or both. These new gaskets are made from aluminium with rubber seal inserts and are made by GM Acdelco. They look very well made so am looking forward to not having o change these gaskets again for the life of the engine.

Awesome work, gaskets are great. Seals for valley cover rubber to plastic adhesion slightly lifting in the corners of the cast. And the plastic cast pins seem to be slightly narrow on the front . Im happy enough it has sealed fine. Thaught it worth the heads up though.
