Burger Motorsports BMS Oil Catch Can – BMW 1/2/3/4 Series (F20/F22/F30/F32, N20/N26)

OVERVIEW

The N20 and N26 turbo four-cylinders are known for oily PCV vapor that collects in the intake and bakes onto the backs of the intake valves, since direct injection never washes them clean. The BMS oil catch can is placed in the PCV line to separate that oil out so it gathers in the can instead of the intake, charge pipes and intercooler.

Built from CNC-machined aluminum with a triple-baffle separator and 16 mm+ inlet and outlet, the can flows more than the factory PCV hose while keeping the closed-loop system intact. The kit comes with a two-piece billet bracket, reducer adapter and silicone hoses, takes about 20 minutes to fit, and is fully reversible. Empty it every 3–6 months by unscrewing the base or using the 1/8" NPT drain plug, and choose a billet or transparent base.
