 I you have a 'leak down test', where compressed air is forced into each cylinder a TDC and the rate of leak is measured, it can tell you whether it's the valves, rings or both. Escaping back out the carbs means inlet valves, out exhaust  means exhaust valves, crank breather means rings. Might save pulling a block and/or head apart uneccessarily.  Jon
