OK, second headgasket in 1000 miles. I think I'm asking a little to much from a stock style head gasket. MLS gasket seems a little hit or mis. I'm thinking about just o ringing my block. Does anybody know where I can rent the grove o matic tool? Yes that does sound funny.:) The car is running MS2 at around 20lbs of boost. No detonation, just need a little more sealing powa.
