You could try preforming a " cylinder leak down test" and then inspect the diff sys of the eng for the escaping air during the test i.e......air in the cooling system will show up as bubbles in the radiator ....air past the rings, piston can be heard in the crank case with the drain plug out of the oil pan,air getting past the vavles , heard in the intake or out of the tail pipe ( depending on with vavle is bad ) .....this can help you narrow it down at least
