im pretty sure its not a cracked head because my mechanic would of told me, most likely something could of happend to the gasket. but as for oil being all in the manafold and exhaust, do you think thats kina a bunch of BS or is that possible as well...i should take a vid of the smoke and post it
You think your mechanic would have told you. Sometimes they are not always truthful. The only way that the gasket could have really messed up is if old age or the previous owner got the car WAYYYY too hot and it messed it up. But if he got tooooo hot it could have cracked the head.
But try the head gasket first.
