Compression test shows low compression#6 cylinder. With new heads would there be blow back to lower block(pistons, rings, seals} are there any products that may restore compression, since vehicle runs smooth with no loss of power. Had check engine light on that indicated misfire, bank 2 downstream oxygen sensor and mass air flow sensor. Mechanic said that with replacement of those parts with new air filter the problem would not be fixed.
have the same problem?
