DESCRIPTION
A piston ring set with the part number 4089347 is a crucial component of a truck's engine. It consists of multiple rings that are placed around the piston to create a seal between the piston and cylinder wall. The primary function of these rings is to prevent combustion gases from leaking into the engine's crankcase and oil from entering the combustion chamber. Additionally, they help regulate oil consumption, reduce friction, and aid in heat transfer. Over time, piston rings can wear out or become damaged which can lead to decreased engine performance, increased oil consumption or even catastrophic failure if not addressed promptly. Therefore, it is important to periodically inspect and replace worn or damaged piston rings with appropriate replacements such as this particular set with part number 4089347.
