i just rebuilt my motor with mahle pistions with 9:1 compression and type s cams. the car was sitting with the motor for about 4 months before starting it up and when i started it up white smoke was shooting out when it was warming up their was a lot of smoke as it got warmer less smoke came out but after the second idle warm up it was still smoking a little bit after it was warmed up what could be the problem?

also the car is running rich is that bad for the car to be driving daily?

thanks

 

was it cold outside?
