Can u get 0 compression out of one cylinder because of a blown headgasket? Cuz i'm hoping that is the problem on my car. I blew it last nite. After shifting into 3rd the car died and a lot of black smoke came out of the exhaust. I'm gonna take the head off tonite to see if it is the headgasket.

 

u can do a leakdown test to see where u are having problems

 

i dont think its your head gasket causing 0 compression mostlikey piston damage/
