Thread: oil blowing out at high speeds

Tweet

No matter when it starts---blow by comes from lack of cylinder sealing--a sraaight round hole with proper cross hatch and compatible rings in good ring lands will control blowby

If it is smoke or oil residue/leaks after camchange----look for proper sealing intake manifold around intake ports, front / rear seals---oil pan leaks--front crank seal----on a cam change you have created an oppurtunity for oil problems at every mating surface except the head gaskets( unless you removed them for spring or valve work)

Guess I found the problem as I did put heavier springs in so now I'll check my head gasket as everything else you mentioned has been checked and rechecked with just one minor thing. That being I have a small leak in my pan. Thanks for the advice.
