I was getting my car finally fixed. i changed the head gasket, valve cover gasket, and my valve lifters. when i got it running it was leaking fuel so i noticed th o-ring was bad. went to autzone and ordered the o-ring. it was supposed to be here last week. but stupid fedex decided it needed to make a stop in spain before it could get back to the U.S. I'm so freaking pissed off right now!!!
