ok, ive tried just about everything i can, and i still dont kno my problem.....at first my oil smelled like gas because i was running rich, i fixed that, now when i rev it up a ton of white smoke comes out the exhaust and keeps coming out for a while, then it stop until i rev it up again, its not coolant i checked that, the smoke smells like oil i think, and it made a coating of black on my exhaust tip!!! if i replace the whole cylinder head will the smoke stop??please HELP

 

white smoke is not oil burning
oil burning is blue
maybe a blown gasket check your coolant for bubbles see if its milky also

 

I'd be willing to bet on the headgasket. You should have a leakdown test done to determine where the leak is.
