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.

Install this on my 2024 Chevy Silverado 2500 hd. Install took approximately 10 minutes. Factory hose came off easier than I expected. After lubricating the O-rings on the new hoses they slipped right on without any issues. Now time will tell what gets filtered out. This catch can should also keep the intake valves a lot cleaner when you do excessive idling.

Easy to install, no need to remove airbox on 2024 GMC 2500 gas. A little expensive for what it is.

Howdy,this is nice product. Well built.I am picky, and the PCV hose was about .5" too short for the canister to be mounted parallel to the ground.It tilts downward towards to the ground from the driver's side to make up for the short hose.I was even going to replace the hose with a longer one myself, but man are these things on tight.Picky, I know, but I paid $159.00 to avoid these kind of cheap issues.

Fit perfectly on my 2020 Silverado 2500hd and after oil change I checked the canister and it works great catching all the gunk going back in intake. Going to install on every vehicle I have. Love it!!
