What would cause this soot to build up on above the intake manifold gasket? Does it need intake and exhaust gaskets?
I’m chasing occasionally knock sound. Oil pressure and level is good, it comes and goes usually at around 1500-2000, and sounds thuddier than a rod knock. I just rehabbed the front of the engine (timing cover seals, water pump, new belts) but I rechecked everything over the weekend to make sure everything was tight. Could it be related?
