The piston rings themselves only cost between $30 to $150 for the parts. However, most of the replacement cost has to do with the labor behind it. Since the piston rings are inside of your engine, this means an auto mechanic will need to remove the engine from your vehicle and disassemble it so they can access the worn-out piston rings.

How much is it to replace piston rings?

On average, a mechanic can charge anywhere from $1,800 to as much as $3,500+ to replace a worn out piston ring/s.

Piston damage or piston wear is a major cause of engine failure. It results in lost compression, increased emissions, leaking of gases from the combustion chamber, and loss of lubrication. When damage involves piston rings, it can mean oil finding its way into the combustion chamber.
