Oil Catch Can, Universal Baffled Catch Can Kit with Breather Filter, 300ml Aluminum Air Oil Separator Tank NBR Fuel Hose Kits for PCV System

The inlet and outlet are marked on the opposite side. I plumbed the fresh air going out the "in" side. (the side with mesh) and the dirty air coming in the "out". As for the product its self it seems great and well built. I did haft to fabricate a different bracket, however that was only due to my application

So what I bought, this EVIL ENERGY oil catch can; well first good reason cause our car was burning oil like crazy and this it’s actually an oil separator, it has to be inserted into the middle of the crankcase breather system. So this line goes back into the port, from the crankcase, and it comes up here, goes through this oil separator, so the catch can, and then out and into the intake manifold. Well before getting to know this will be the solution to our problem I learned what is an oil catch tank (oil catch can) is a device that is fitted into the cam/crank case ventilation system on a car. Installing an oil catch tank (can) aims to reduce the amount of oil vapors re-circulated into the intake of the engine. All engines have some amount of blowby and even if that amount is small, capturing oil before it gets into the intake is a plus. As oil enters the intake it has a tendency to stick to the back of the intake valves creating carbon build up. So that is why is so important to have one installed. The only thing I would recommend to get is a new hose line It was simple to installed , and will help keep your engine turning despite big power mods. Oil in your intake is never a good thing. Recommended we all need one

surprisingly made from billet aluminum, I bought some real vaccum hose and gear clamps to make it work better. The hose it came with were terrible. If you use a little pipe thread sealant tape it seals and holds a vaccum like a champ. it catches oil and water just like it promised. Amazing results and peace of mind for the price. Add a little steel wool from home depot in the baffles and it works even better.

I chose to try this oil catch can even though it is half or a third of the price of brands from other suppliers and was really surprised at the high quality of the parts. Even the hose supplied was a proper fuel hose type. Installation was super easy and everything fit well. I used a bit of silicone grease on the threads of the canister to help stop the binding. The kit did not come with teflon tape for the bars fittings but probably not needed as there are supplied o-rings for the seal at the fittings anyway. I’d recommend the kit

The EVIL ENERGY universal baffled oil catch can has worked well so far and does exactly what it’s supposed to do. The build quality is good for the price point—the aluminum can feels sturdy, the fittings seal well, and nothing about it feels cheap or poorly made. The internal baffling appears effective, and it’s clearly designed to separate oil vapor and moisture rather than just being an empty container. Installation is straightforward, especially for a universal kit. The included hardware and NBR fuel hose are usable and functional, but I would recommend getting additional fuel hose. Depending on your engine bay layout and where you want to mount the can cleanly, the included hose may be a little short. It works, but extra length makes routing much cleaner and avoids tight bends or stress on the fittings. In actual use, the catch can does its job. It collects oil residue and blow-by that would otherwise be going back into the intake, which is exactly what you want—especially on higher-mileage or performance-oriented engines. The 300ml capacity is a good size: compact enough to mount easily, but large enough that you’re not constantly emptying it. Overall, this is a good value catch can. It works well, looks decent, and performs its intended function without issues. Just plan ahead and buy some extra fuel line to make installation easier and cleaner. For the money, it’s a solid option and I’d buy it again.
