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.

Installed on my 2018 Silverado 5.3, I don’t drive this pickup much so I only had to empty the catch can maybe once a month during the summer, but now that’s it’s cold out and the pickup idles some I clean it about twice a month.

This was easy to install. Watch the video here (top of page) and it's pretty simple. After about 5 weeks, this device captured about half the holding capacity. That oil would have gone into the air intake and onto the valve stems where it would've been burned and left carbon deposits. Instead, the oil gets recycled. Just one thing GM should've added to their vehicles. This is installed on a 2018 Sierra 6.2L (L86) engine.

Catches a surprising amount or oil. There is a link to a video on how to install. Recommend installing while engine is cold. Should take less than 20 mins if you have the tools ready.

Great quality and easy install. Fits perfectly. Performs great and I now have them in my trucks as well. I just ordered the can extension so I don’t have to check it as often. It’s a must have for these direct injection engines in my opinion.

I used a cheaper cath can on my last truck which was a 2015 Silverado. I got a 2017 GMC and installed this right away. The directions were easy to follow and it's working as advertised. I would definatly get this over a cheap can you'll really undestand if you made the mistake I did because not only was the cheap one hard to install it wasn't getting anything in it. This is the exact oppisite I think it was about a 15 minute job and I have to enmpty it because it works.

Yes, you can get cheaper oil catch cans if you want to build your own. There are some really nice make your own kits out there that will save you some money.However, if you're like me and you like easy, plug & play stuff, J&L is the only way to go. OE style connectors, detailed install videos, most of their cans can be installed in 10 to 15 minutes tops, what's not to love? Plus the added benefit of having your OE PCV hose around just in case.After watching their video of how much oil the Jeep 3.6 pukes out I need one for my Gladiator now. I'll order it this weekend.

Overall, this catch can is great. The price is reasonable and the build quality is excellent. The threading on the can is very good and it operates smoothly. With the mounting bracket placement, it is easy to access the can to empty it out. The installation was super easy and the included instructions are easy to follow. I installed this into a 2014 Chevrolet Silverado LTZ Z71, and so far it's been great. I did take a peek to see if it is catching any oil, and it is!
