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.


Real Performance Requires Real Filtration

Most engines today are built for efficiency, not longevity, and blow-by is the price you quietly pay. Oil vapor circulates back into your intake system, coating valves and disrupting combustion over time. Left unchecked, it leads to carbon buildup, reduced performance, and costly maintenance down the road.

That’s why we built the J&L oil separator: to stop the damage before it ever starts. With thousands of satisfied drivers across the U.S., our systems are trusted on streets, tracks, and trails alike. Whether you're protecting a turbocharged daily or a tuned weekend warrior, we help keep engines clean.

Oil Separator for Vehicle

Oil Separator for Car

If you're driving a modern performance car, you're likely already dealing with blow-by even if you can't see it. Direct-injection engines are more prone to carbon buildup, especially under boost or heavy throttle.

A J&L oil catch can traps harmful oil vapors before they reach your intake, reducing carbon and protecting power. Our kits are engineered for factory-like fitment, so you can install them without cutting or tuning. They’re the kind of upgrade you don’t notice until you realize how clean your engine runs year after year.

Whether you’re pushing a V8 muscle car or a high-strung turbo four, this is a performance essential.

Oil Separator for Truck

Trucks do the heavy lifting—towing, hauling, crawling—and blow-by hits even harder under those conditions. With more crankcase pressure comes more oil mist, and that mist ends up sticking to intake valves and throttle bodies.

The J&L oil separator is your first line of defense, stopping contaminants before they cycle through again. We build each system for the engine it’s going on, so you get a clean installation and reliable performance. From LT and Hemi to EcoBoost, daily driving to trail use, these kits are built for real-world abuse.

Our models are a high-efficiency air/oil separator, offering maximum filtration under high load.
