Hi guys. I just had my vq40 completely rebuilt and after 2500 miles i started getting white smoke out of the exhaust. Brought it back and the found a bad valve seal in #6. The pulled both heads and replaced all the seals pcv and both head gaskets. Upon start up it smokes for about 5mins then it goes away. There hasnt been any loss of power. What else could it be? Thanks guys.
