Ive read about valve stem seals vs rings going bad. My car doesnt smoke ALL the time constantly. It smokes on start up and when im idling, and sometimes when i push down the throttle hard. The engine runs FINE, It still has alot of power. Whats also weird is when i changed the oil, it smells like the new oil being burned, and when i put seafoam in the crankase, it smelled like that being burned... So maybe everytime i fill it , the oil or seafoam seeps past the valve stem seals to the combustion chamber? I guess it makes sense because you fill it from the top, and thats where the seals are. I hope im right.
