need help please!!!! I've replace the head gasket ,got the head shave and pressure tested.Put everything back together. There is still white smoke coming out of the tail pipe? Is there a possibility that there is some water or coolant in the cat or exhaust?

 

is the gasket brand new?

 

have you driven the car since the head gasket replacement? might just be coolant sitting in the piston if you just started it up. if your driving it, and its still blowing white smoke, you might have blown it again already.

 

no i haven't drove it yet. but i let it ran for about 15 min. When i started it blow a little white smoke but when it's at accelarate it blow alot. Do you think there is still coolant in the piston?

 

yes the gasket is new.
