Measure the piston at its gauge point with a micrometer to determine if it has worn significantly. In cases of extreme detonation or heat, the skirts could have collapsed which will show on the gauge.

What are the symptoms of bad piston rings?

Here is a list of the most common symptoms for bad piston rings:White or gray exhaust smoke.Excessive oil consumption.Low power for acceleration.Overall loss of power or poor performance.

What happens if a piston blown?

In either case, the engine will stop immediately and the hot oil escape through the hole in block or crankcase and onto the hot exhaust causing a lot of blue smoke or even a fire. Another form of engine failure is a broken valve punching a hole through the top of a piston.
