How To Replace Engine Piston Rings
Piston Ring Replacement Car Engine Piston Ring Replacing Procedure Helpful Information If new piston rings are installed without machine work it will make the situation worse due to the oblong wear pattern the cylinder walls produced during normal long term operations. In other words, new piston rings are perfectly round with no wear, if they are installed into an oval shaped cylinder (worn) the ring operation failure will be amplified. An engine's piston rings are used to seal the piston to the cylinder wall during the compression stroke. When a combustion event occurs these rings are forced against the engine block cylinder walls to help contain the energy that is released. Most engine pistons contain three separate rings that perform unique tasks. The first ring or top ring is the main combustion ring that takes the brunt of the force as the piston is thrust downward. The second combustion ring acts as an overflow or secondary confinement ring that aids in the service ...
