How often should I drain the oil separator?

J&L recommends draining the oil separator every 2,000 to 3,000 miles. Regular draining prevents the tank from overfilling and ensures optimal performance.

What is the capacity of the oil separator's tank?

The tank holds 3 ounces of fluid. While this may not seem like much, it is designed to handle the typical amount of oil that accumulates in a PCV system between recommended drain intervals.

What maintenance is required for the J&L oil separator?

The primary maintenance task is to drain the accumulated oil regularly. The manufacturer also recommends inspecting the O-ring seal periodically to ensure it remains in good condition and prevents leaks.

About this part

Product Details

During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors can gather/accumulate in your 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, we have developed an oil separator of our 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 every 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 tank holds 3 oz of fluid, while that may not sound like a lot, you shouldn’t see that much oil in your PCV system. Drain it every 2000-3000 miles and you will never come close to filling it.
