J&L Oil Separator Co. — Proven Protection for Modern Engines

Oil‑laden blow‑by covers intake valves, dilutes fuel, and steals horsepower. The J&L oil separator captures that mist before it can cycle back through your engine. Each billet‑aluminum canister routes crankcase vapor through a filter that traps oil yet lets clean air keep moving. The install takes minutes with OEM‑style fittings and leaves no permanent changes. Every J&L oil catch can is engineered, machined, and assembled in the USA, backed by a lifetime warranty—peace of mind on the street or track.
