A bit OT, but what would you do to an engine that is getting low compression across the board? Leak down test to see where the leakage is ocurring and go from there? Likely that the piston rings need replacement? Bore/hone the cylinders? Rebuild the head?

yeah usually the rings are leaking a little bit by... the best thing to do is get new rings hone the walls, wouldnt bore it unless you have to, change all the bearings since you have it apart new head gasket and goooooooooooooooooooo!!!!
