I disassembled the engine. made a list of parts. I looked up the torque values online and using the new parts reassembled the engine. It fired right off and ran smooth. The parts I received from Replacement parts fit perfectly and the price was right. They were delivered in a timely manner.

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.

Exhaust valve guide migrated up & interfered with the rocker arm movement.

Pressed the valve guide back in place. Staked it on both ends. Re assembled with the new parts, & the engine is back running as it should. I'll monitor the guide periodically to check for future issues. If it does not stay in place the head will need replacing.
