| During the process of venting crankcase pressure back through your intake track, large amounts of oil—in the form of vapors—surface in your intake tube and intake manifold runners. These vapors can even dilute your gas, lowering its octane level. This happens on all engines and is even worse with forced-induction vehicles (supercharged and turbocharged) as crankcase pressures are increased. To combat this, JLT Performance has developed an oil separator of the company’s 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-inch thick, 1/16th-inch aluminum honeycomb filter where they grow ever larger and then fall into the bottom. By the time the oil gets through the filter, it’s too heavy to be passed into the intake. The tank holds 3 ounces of fluid; while that may not sound like a lot, you shouldn’t see that much oil in your PCV system. Drain it every 2,000-3,000 miles, and you will never come close to filling it.
