During the process of venting crankcase pressure back through your intake track, large amounts of oil in the form of vapors can coat your blower rotors, intake valves, intercooler fins and even dilute your gas lowering its octane level. This happens on all engines and is even worse when supercharged as crankcase pressures are increased.
To combat this, we have developed an oil separator of our own design that filters / separates the oil in the vapor and deposits it into the catch can instead of circulating through your engines intake system.
A filter on the inlet side of the oil catch can traps fine oil vapors and releases them once heavy enough to fall. 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 2000-2500 miles on most applications and you will never come close to filling it. Average colletion for most applications is roughly an ounce every 1000 miles.
How to Check
To determine if your vehicle needs an Oil Separator, locate where the PCV Valve connects to your intake manifold, remove the line and inspect it.. If you see ANY oil residue in these areas, your vehicle would benefit from an oil separator.
If these areas are completely dry and no oil residue is present, you DON’T need and Oil Separator. It is that simple.
Our J&L Oil Separator is designed to work on any engine, but we have made it easy for many of the popular Ford, Mopar and GM vehicles. Offered as a plug and play set up for many applications with factory PCV hard lines already attached. Simply unplug your stock line and attach the new set up, easy as that.
When you’re ready to empty the tank, just undo the clips on the factory lines and remove the entire line, unscrew the tank, empty and reinstall. This will take less than 1 minute to complete, too easy!!
