J&L

Is your engine getting oil in the intake, and do you want to keep it cleaner inside? J&L makes oil separators, also known as catch cans, that collect oil and moisture from the crankcase ventilation before it reaches the intake. Here you’ll find vehicle-specific kits for popular V8, turbo and truck engines, as well as universal solutions for your own project.

American oil separator specialist

J&L Oil Separator Co. is an American brand that specialises in one product group: oil separators. When the engine runs, gases are pushed past the piston rings into the crankcase. The PCV system routes them back into the intake, carrying oil vapour and moisture with them. Over time this can cause deposits in the intake and on the valves, especially on direct-injection engines. J&L develops separators that catch the oil on the way and makes kits with hoses and brackets tailored to each engine.

J&L’s key products

The core is the J&L 3.0 oil separators, a series with a baffle system inside the can that separates oil from the airflow. They are available as vehicle-specific kits for the Ford Mustang and F-150, Chevrolet Camaro, Corvette and Silverado, Dodge and Ram, and Jeep Wrangler, among others, often in versions for both the PCV side and the driver side. The kits come with brackets and hoses to fit the engine bay. Universal separators are available for your own projects, in several finishes such as black and clear anodised. See each product for fitment.

Frequently asked questions

Why does my engine need an oil separator?

The crankcase ventilation routes oil vapour back into the intake. An oil separator collects the oil so the intake and valves stay cleaner. This is especially relevant on direct-injection, turbocharged or supercharged engines.

How often should a J&L catch can be emptied?

It depends on the engine, driving and season. Check the can regularly at first, for example at every fill-up or every couple of weeks, to learn how quickly it fills. More moisture may collect in winter.
