How would the HG produce a boost leak??? The air has to be entering the cylinderto go out the gasket. If the air is entering the cylinder, it would not produce boost leak symptoms of a poor A/F ratio correct??? The gasket is not totally blown. The car does not leak coolant. It pushed some out the back of cylinder 1 under 25psi, that is it. It didn't even loose enough coolant to justify reffilling. The system was full and there was still some left in the overflow. I am guessing that the head could be/been warped. After the 6 bolt was thrown in, compression was 140-140-130-90 (4-1). It also blew the coolant out of the #1 cylinder. It was definitly not a tuning issue as only 1.X count of knock was recorded on the first pull. I richened it a bit and the car pushed coolant getting 2.X counts of knock. I am guessing the warped head expanded enough to blow coolant by the second time after the car was heated up. Maybe we will try a comp test again and see how bad he is now...
