I have this wierd puff of smoke if i drive the car hard.It happens after the car has been sitting for 30 minutes or so.Its a quick little white puff sometimes small and some times big.I kno that oil is bluish black when coming out of the tailpipe and coolant is white and smells sweet but this has neither those smells.This car doesnt burn any oil and its even golden when it comes down to doing the change and coolant is always topped off.

Motor still runs strong

I seem to remember similar posts like this in the past.

Most people who replied were saying it was a normal part of most b-series...but I don't know any better so don't quote me on that.

if it only does it after startup and doesnt do it anymore when the motor is completely warm, then its most likely condensation that built up in the exhaust while it sat and cooled down. next time it does it watch the smoke, if it lingers in the air and doesnt dissipate it could be oil (btw oil is white/grey not black, fuel is black) but if it does dissipate then it's water vapor

 

its not cold outside tho thats the thing so im thinking vale stem seals

 

Fouled plug?
