What are your compression numbers? I bet it is valve stem seals. You may have bent a valve with that witchdoctor treatment. Don't put anything in your engine other than gas and oil. It often causes problems and seldom fixes anything. Good gas in a good running engine will decarbon your combustion chambers.
You DID check compression BEFORE putting money into your engine, right?
