Where do you guys get your parts from (HG's, studs, etc.)? If the head gasket blew though wouldn't there be an indication of oils or gas in the anti freeze? Or even a gunky buildup of sludge on the underside of the radiator cap, in the radiator, and over flow? I'm just curious because I didn't see any of that when I opened them up. I'm going to but in an aluminum radiator anyway, but I figured I'd ask. Liek I said I 'm a Subaru guy and now more about those than I do about this car.
