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 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 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.
Our Oil Separators are easy install, service and flat out work! Many use OEM hoses or come complete with all hoses, custom brackets and hardware for an OEM look. Retain stock hose if you ever return to stock.

Watched the install video and 15 minutes later I had it installed. Only thing I did different was that I covered the tubing with AC pipe insulation tubing before installing. This was done to midigate any potental hissing sounds that some complain about. I don't hear any hissing coming from my system.
Got the package, pretty quick shipping.
Watched an install video just to be sure. Seemed to go in SUPER easy. Even called with a concern and their customer service was stellar.
Have no issues purchasing again should the need arise.
I will be buying the 3 OZ extension cup just to be safe.
J&L oil separator is a quality product, love the ease of installation just plug and play. I will continue purchasing their products going forward.
I had concerns about hissing or vacuumed leaks from some reviews and YouTube videos. I followed the instructions and lubed the inside of the connections very well. Everything went as well as the video as far as installation. I have no hissing. No vacuumed leaks. I can’t tell I even put it on. Gas mileage the same. It’s been on about 500 miles. I’m glad I spent the money and went with a product that has the same oem fittings. This makes installation great. Just Lube the inside of your connections. I’m very happy !
Inside the oil separator there is a filter. The filtered side of the can should always go to the PCV valve or “dirty” connection. The filter is what turns the oil vapor into liquid form to be collected in the basin of the unit. You want this to happen as it is entering the can. The open port will run to your intake.
In most cases you only need an oil separator on the PCV side (dirty side) of the engine. This is the side that is under vacuum/suction most of the time while the vehicle is running and driving. The clean side typically is only used for venting when the PCV valve is closed which is under moderate to high acceleration.
Some turbo vehicles can see oil in the clean side, such as Ecoboost F-150’s when they are exposed to frequent towing conditions.
On non-turbo applications anything short of road course racing you typically will not see a drop of collection out of the clean side.
For most Ford applications there is a grey or green tab, you press in this larger tab. It is a button; it will release the fitting and you pull up on the fitting with the button pressed. ***DO NOT REMOVE THE CLIPS FROM THE FITTING! YOU WILL BREAK THEM!!***
For GMC/Chevy applications there is a single button release. This release and the location of some of these fittings can be tricky. You must press the bottom squarely and pull the fitting straight off. Many people make the mistake of pressing the button too hard and it flexes the release. Take your time and it will release. The 5.3L intake fittings are the toughest due to their location.
Most applications average about an ounce of oil every thousand miles. However, there are many factors in collection rate as every single engine is different. Factors such as driving style, climate, engine condition, oil level all vary and effect collection rate.
People in cold climates will have to check their oil separator more often in the winter months due to condensation build up occurring in the oil separator itself. In these months, the air entering the can is significantly hotter than the ambient air temp. This results in condensation build up (think hot shower in a cold bathroom).
We recommend everyone to check their oil separator at 500-1000 miles of driving to get an idea of how often it needs to be serviced. The can holds 3 ounces without the optional extension.

The specs on the screws are M4 x .7 x 10mm, they can be found at just about any hardware store.
Sometimes when the oil separator is over tightened it can be tough to remove; also some oil separators are much more accessible once installed than others.
If you are having trouble removing the oil separator reservoir, try removing it from the bracket or even vehicle to get a better grip on it. For units that are really tough, we recommend a rubber oil filter strap wrench. You can use this in combination with a rag and typically remove them without damage.
When reinstalling the can bottom, treat it like an oil filter. Screw the can to the bottom of the O-ring. Give it another ¾ to 1 full turn. No more, no less.
No! Dispose of this nasty oil that is mixed with fuel, water and everything else where you would dispose of your oil change oil. Many auto parts stores will take your old oil for free of charge.
If you read the fine print on any warranty contract you will find a lot of reasons your warranty can become void; installing aftermarket parts can be one of them.
However, per the Magnuson–Moss Warranty Act proof would have to be provided that the after-market part caused the failure.
