So a few weeks ago I was driving home from the mall and I started to hear this bad tapping sound coming from the engine. And I know it wasnt a rod knock because I already had one of them. It sounded like it was coming from the head and sure enough she just shut off on me and I couldn't turn it back on. It didnt even crank. Prior to this she would overheat a little bit but I would pull over and check her out. I'm asking is what could of caused this big mess?? Overheating? I probly answered my own question but I have to know for warrenty purposes so they dont screw me. Any info would help me out. Thanks in advance!
