Re: Excessive Blowby Advice
Just so you know , a small block Chevy "rear main seal" CANNOT be pushed out by blow by. The purpose of the rear main seal is to keep oil pressure to the rear thrust bearing from leaking externally. that's all.
All the other seal can be pushed out with excess crankcase pressure, oil pan gasket , valve cover gaskets , timing cover gasket.
