Engine cylinder condition can be analyzed with controlled pressure air through the engine cylinder precombustion chamber. Special Instruction (GMG00694) explains the procedure.

Air escaping from the exhaust opening indicates exhaust valve leakage. Air escaping from the air inlet indicates inlet valve leakage. If air escapes from the crankcase breather during this test, it is an indication of piston, rings and/or liner faults.
