21 H.P. Briggs & Stratton engine on Craftsman mower began smoking heavily while cutting grass.
Since the blue smoke from the exhaust smelled like burning oil I was certain the problem was a blown cylinder head gasket or possibly a leaking intake valve seal. I ordered both parts, which were shipped the same day, and disassembled the cylinder head to find the cause. As I suspected, the head gasket was blown and sucking oil from the valve gallery into the combustion chamber. I installed the new gasket and valve seal, torqued the head to 170 inch lbs. assembled all parts and started the engine, which ran perfectly . I'm pleased with the quick service and exact replacement parts from eReplacementParts.com. and will use them again if I have further problems.
