What is the purpose of an oil ring assembly?

The oil ring assembly's primary job is to scrape excess oil from the cylinder walls as the piston moves down. This prevents oil from entering the combustion chamber, which helps control oil consumption and reduces exhaust smoke.

Why is the chrome plating on the rings important?

Chrome plating on piston rings provides a harder, more durable surface. This increases resistance to wear and scuffing, helping the rings last longer and maintain a good seal against the cylinder wall over time.

What does 'standard tension' mean for an oil ring?

Standard tension refers to the spring tension of the oil ring. This setting is designed to provide a good balance of sealing ability and reduced drag on the cylinder wall, suitable for most general engine rebuilds.
