EVIL ENERGY Oil Catch Can, Universal Baffled Catch Can Kit with NBR Fuel Hose, 300ml Aluminum Air Oil Separator Tank for PCV System Red

I recently installed the Evil Catch Can on my 2006 Chevy Silverado Crew Cab with the LM7 5.3L V8 (311,000 miles on the clock), and I have to say this is an outstanding product. The build quality is solid, the fittings are secure, and the installation process was straightforward. Immediately, I could see the value in running one of these, especially on a higher-mileage engine like mine where crankcase vapors are more of a concern. What really stands out is how effective it is at trapping oil and contaminants that would otherwise end up recirculating through the intake. That’s critical for keeping carbon buildup down, maintaining throttle body cleanliness, and ultimately extending the life of the engine. I plan on installing a second unit so that each bank of my V8 is covered. To me, this makes perfect sense, since both sides of the engine generate blow-by gasses. It honestly baffles me why so many installs I see only utilize a single catch can on the driver’s side. Having one on both sides feels like the most complete way to protect the motor, especially as the miles rack up. Overall, I couldn’t be happier with the purchase. For anyone running an LS-based motor, whether stock or with miles like mine, I’d strongly recommend the Evil Catch Can setup. It’s a small investment that pays off in cleaner internals and added peace of mind.

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.

The quality is very good an function very well no oil in my intake and all items like hoses and clamps are great as well had it for a year not disappointed at all

I don’t often leave reviews on Amazon, and this is the first time I’ve touched photos, but this is really just to quash some of the reviews I’ve seen where people saying, you know, the quality of this isn’t great. It, to me, for the money, it’s crazily good. It’s a piece of aluminium billet. It’s beautifully engineered. It feels really nice to screw the cap back in and out. Everything’s tight. You can even see the machining marks on it. It looks really, really good. I think the only thing to a couple of the reviews have been negative on quality, might that have been related to the vacuum nipples and the little bracket that sits behind it, and it goes on to probably not quite matching the quality of the actual can itself, but that said, for the money, I can’t believe the quality of this, and I’ve seen other things that are significantly more. I’m very, very pleased with it, and I am fussy, and very, very happy with it, and if you’re thinking about a catch can and perhaps you don’t want to spend as much money as Moroso or another brand, I think this one, for a 300ml catch can, is a really good buy, and would definitely buy these Evil Energy products again after this. Yeah, I think this represents value and quality, and for the price, I just don’t think I can fault it.

Great product, showing this thing to other people has probably made close to 10 sales for this company. Looks good performs great, an price point is spot on

I installed this oil catch can on my vehicle to help reduce oil blow-by and carbon buildup, and it’s already proving to be a great investment. For the price, the quality is surprisingly good — solid aluminum construction, tight fittings, and no cheap plastic parts. Installation was straightforward. It came with all the necessary hoses and clamps, though I did upgrade the hose for a tighter seal (which is pretty common with these kits). Once in place, it fit neatly in the engine bay and hasn’t leaked or loosened after a few weeks of daily driving. After a few hundred miles, I checked the can and it was already collecting a noticeable amount of oil vapor — exactly what it’s supposed to do. This tells me it’s doing its job and keeping that gunk out of my intake system.

Well....out of the box it looks like a nice catch can. I got this after watching some videos with the same truck platform. I have a 2006 Avalanche. The bracket will not allow for a good spot to mount the can. I had to drill a hole lower in the bracket to get it to mount onto the engine, holes were to close together. This bracket needs to be maybe 4" taller to allow the can to unscrew. With it how they made it, the can sits on the B+ cable. Tried to move that around but its not budging.

Great Product. Some sharp edges, but very nice quality. Cut dogleg off supplied aluminum bracket with a hacksaw and bend at a 90 as shown. Mount to frame as shown with Honda bolt, then drill hole in bracket and car frame for second stability sheet metal screw (not supplied) Engine cover still comes off nicely. Engine dipstick and radiator reservoir 100% accessible. Hood prop clears oil can nicely and dip stick is easy to reach as is can bottom to spin off for maintenance. All hoses are relaxed with no pinch points. This method keeps original PCV hose in tact for quick removal in case of warranty work. O rings supplied are a little small, difficult to get over threaded fitting but they work. Be careful not to over tighten fittings or you'll damage the O rings. The coalescing steel wool supplied is plentiful, enough to change out 3 times. Overall a fun install. Highly recommended!
