[QUOTE="SRAD97750, post: 198435, member: 425"] The answer to this specific question is a simple [I]leakdown compression test[/I]. It requires a tool and air compressor. This will point you in the direction of valves or rings, if there is an out of spec reading. Aside from this, you can only tell if a piston/ring/cylinder relationship is 'working out' by routine disassembly and inspection. -BIG DAN:thumb: [/QUOTE]
