Why J&L OSC?
Easy plug and play kits. Super easy to check and empty. Many kits use OEM hoses or come complete with all hoses, custom brackets, and hardware. Retain stock hose if you ever return to stock. No hoses running all over your engine compartment. OEM look and quality. Perfect size, not too small, and not huge by any means.
How does it work?
During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens on all engines and is even worse with forced inducted vehicles (supercharged and turbocharged) as crankcase pressures are increased. To combat this, J&L has developed an oil separator of their own design. Milled from solid billet aluminum, this is a rock solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O-ring seal to prevent any leaks.
Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow even larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake. The can holds 3oz of fluid, while that may not sound like a lot, you shouldnt see that much oil in your PCV system. Drain it every 5000-7000 miles and you will never come close to filling it.
Note: We suggest draining catch can every 3000-5000 miles or inspecting each oil change, fluid contents can vary between spirited driving.
