not everything done to this motor was done by the same person. the head was done by carquest and they said everything was fine. The valves seals r new also. The bottom end is where i think everything is happenin. um.. as far as the pcv set up where is the longer hose supposed yo go? i know the short one goes to the top of the block but wat about the long one? valve cover? intake mani? Im not driving my car and all the walls look perfect. I think the oil rings on the piston most likely got messed up while this guy was pushing them in. I am the one that personally gapped them to make sure and yes they were compressed upon installation. Just while pushing them in he had trouble because they wouldnt just slide in...
