Chevrolet Silverado 1500 Oil Separator - J&L - 3.0 PCV Side - Clear Anodized (2014–2018) is a compact, high-quality PCV oil catcher designed to keep oil vapors out of the intake and protect your 4.3L V6. It’s a direct-fit J&L unit machined from billet aluminum for durability.

This oil separator uses a multistage filtration system to capture oil vapor before it reaches the intake tract. A fine stainless-steel mesh collects the smallest droplets, while a 1/2" thick 1/16" aluminum honeycomb section grows droplets until they fall into the removable reservoir. The tank holds approximately 3 oz and features a knurled base for easy draining and an O-ring seal to prevent leaks. Quick-connect PCV fittings simplify installation on the PCV side of the engine for 2014–2018 Silverado 1500 4.3L applications.
