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 gather/accumulate in your intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens in 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. This product is NOT CARB (California Air Resource Board) Exempt. It is not for legal sale or use in the state of CA or any other states adopting CA emission standards and require a CA Executive Order (EO) number.

Frequently Asked Questions
How often do I need to check my oil separator?
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 500-1000 miles after initial installation to get an idea of how often it needs to be serviced. The can holds 3 ounces without the optional extension.
Do I need an oil separator on both sides of my engine?
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 heavy 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.
What do I do with the oil that collects in the oil separator, can I put it back in the engine?
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.

Worth it if you have a Nissan Frontier 3.8l 2022. This will keep all that unwanted oil out of engine! Helps catch all the blow by!
Skeeter –
This catch can will definitely filter an oil/gas/water mixture that would have otherwise been dumbed back through the intake and down behind the valves. It only took 500 miles to collect a little. Ore than an ounce of gunk. Hopefully, it will keep carbon build up at bay for a longer engine life.
Norberto Perez –
Excellent product, works great, hoses connections doesn’t look so great. I used a 3/8″ hose and re-routed my way. Looks much better and almost OEM, only need about 5 ft.

Installed within 20 mins. Nice design and very happy with the purchase. On my 2023 Nissan Frontier. It does collect the blow by which would get recirculate back into the engine.
Harold S. –
It works, easy to install, meets expectations.
JOHN B. –
Only took 5 minutes to install and looks great.
PD –
Perfect piece of mind. Bought this one for my Nissan Frontier. This is the second time running this, I had one on my F150 and they do keep out the oil that blows by! Would recommend
Mac –
First time using/installing an oil separator and this took no longer than 10 min to install…very easy to install! I have a 2022 Nissan Frontier Pro-4X and is the first time dealing with a GDI engine. So, I figured I’d give this a try and seems to be working. I have checked a few times since installing and have a little bit of oily residue from the blowby in the can. It’s not enough to dump it but it’s good knowing that the oily vapor is no longer being burned in the engine and carbonizing on the intake valve.Also, love that this device is made in the USA!
Prime Buyer –
Just passing the information along that this product fit my new 2025 Nissan Frontier.The separator has performed well on my Bronco Sport so it was an easy choice to make J&L the catch can of choice for the Frontier.
