GMC Sierra 1500 Oil Separator - J&L - 3.0 PCV Side - Black Anodized - `14-`18 is a purpose-built oil separator engineered for the 4.3L V6 in 2014–2018 Sierra/Silverado trucks. It reduces oil vapor sent back through the intake to help keep intake tubes and runners cleaner.

Machined from solid billet aluminum with a black anodized finish, the J&L 3.0 uses multistage filtration to capture fine oil vapors and return clean air to the intake. A fine stainless steel mesh catches the smallest particles, which then coalesce on a 1/2" thick, 1/16" aluminum honeycomb so droplets form and drop into the sump. The removable, knurled base with an O-ring seal allows easy draining and minimizes the chance of leaks. The tank holds about 3 oz; draining every 2,000–3,000 miles will keep the unit operating as intended. Quick-connect PCV fittings provide a straightforward, vehicle-specific installation for the 4.3L V6.
