2006 gto low compression
I have a 2006 gto with a p1sc procharger pushing 7 psi of boost, and a cat back exhaust. My problem is that i have low compression on all 4 cylinders on the driver side bank. All cylinders have different compression as well. The passenger side cylinders have good compression on all 4 cylinders. i did a leak down test and could hear the air going into the oil pan through the valve covers. i also replaced the head gaskets and that made no difference at all. could i have broken the ring lands on the piston only on the driver side? what else could be my problem? thank you, any help is appreciated.
