Piston ring is broken what symptom phenomenon does leak have?
The bad piston ring​ may be related to the air leakage caused by its wear or coke connection with the piston ring groove. If after cutting off a cylinder, the exhaust gas no longer from the oil or vent vent, the cylinder piston is not good use.

The piston ring is the core component of the fuel engine. It seals the fuel gas with the cylinder, piston, and cylinder wall. Piston ring functions include four functions: sealing, adjusting engine oil (oil control), heat conduction (heat transfer), and guide (support).
