Not Ranked

Sounds like the same basic thing that happened to me last year. Bad gas caused detonation, and broke a land on the #4 piston. The broken bits stayed in place luckily.
Pull the pcv out (if you are using one) when the engine is running to get an idea on the amount of blowby. If is a lot chances are it is a broken piston.
Sorry Tommy
