hey guys, i want you guys to tell me what might be wrong with my car or is it normal.
i did a cold start after the car has been sitting for a night, no smoke would come out of the exhaust pipe however, when i rev the car high (I know i shouldnt) there would be whitish- blue smoke coming out of the exhaust.
but when the car WARMS UP, no matter how much i rev the car, NO smoke would come out.
I did another test when the car was cold again but only after it has been sitting for 3-4 hours but no smoke would come out.

in conclusion, only smoke comes out when revved cold. NO smoke when idle (cold) and when warmed up.
Is it just condensation? or is it my head gasket?
