Chevrolet Silverado 1500 Oil Separator - J&L - 3.0 PCV Side - Black Anodized - `14-`18. A compact, engine-mounted oil separator designed for the 2014–2018 Silverado/Sierra 1500 4.3L V6 to reduce oil vapor passing back into the intake and help keep intake tracts cleaner.

Machined from solid billet aluminum and finished in durable black anodize, this J&L 3.0 PCV-side unit uses multi-stage filtration to capture oil vapors before they reach the intake. A fine mesh stainless screen and a 1/2" thick 1/16" aluminum honeycomb media collect droplets until they grow heavy enough to fall into the removable tank. The knurled base allows easy draining, and an O-ring seal prevents leaks. The unit holds roughly 3 oz and is fitted with quick-connect PCV fittings for direct replacement on compatible trucks. Recommended service interval for draining is about every 2,000–3,000 miles under normal use.
