Pistons and liners are key components of any internal combustion engine. The piston moves up and down within the cylinder, compressing fuel and air before ignition. The liner, also known as the cylinder sleeve, provides a smooth surface for the piston to move against. However, when these parts fail, it can lead to serious engine damage. Common causes of failure include overheating, lack of lubrication or poor maintenance. Symptoms of failure may include decreased engine performance, excessive oil consumption or even complete engine seizure. If you suspect that your pistons or liners are failing (Part Number: 985579), it is important to have them inspected by a qualified mechanic as soon as possible to prevent further damage to your truck's engine.
