I was looking the car over today and thinking about what could be wrong with my car, for the heck of it I thought I check the antifreeze. I opened up and there was pressure and the antifreeze was all gone, I know that there was some in it the other day. I think I have a bad headgasket? That would explain the white smoke, right? What do you guys think? Wouldnt that explain the pressure in the crankcase also?
