Im not to worryed about the HG its not my car (cant see it from my house) lol. But on a real note. I have a extra HG sitting at my house im giving him and he's picking up some arp's also. It just sucks cause the guy that he bought the engine from said it has new rings and bearings. So that prob a lie. Atleast we found the prob.

Water wetter+Distilled Water > Antifreeze

^ SoCal weather ofcourse...lol
