Carrillo Oil Ring 2 Piece Diesel 4.035 Bore 3.0mm *Single Ring*

This is a Carrillo 2-piece diesel oil ring, designed for a 4.035 inch bore with a 3.0mm width. It's a single ring, meaning it's just the oil control ring component for a piston assembly. Carrillo is known for making well-built internal engine components, and this oil ring is no different. It's built to handle the demands of diesel engines, helping to control oil consumption and maintain proper cylinder sealing.

When you're rebuilding a diesel engine, getting the right piston rings is crucial for performance and longevity. This particular oil ring is designed to fit specific applications where a 4.035 inch bore and a 3.0mm oil ring width are called for. Proper installation is key to ensuring it functions as intended, helping to keep oil where it belongs and out of the combustion chamber. This helps prevent issues like oil fouling spark plugs (in gasoline engines) or excessive smoke and blow-by in diesels.
