The APR Catch Can System with PCV Plate is a comprehensive upgrade to your engine's Positive Crank Ventilation (PCV) system. This factory-racecar-inspired system takes a multi-step approach to addressing several performance-robbing issues, and critical engine safety concerns, with the factory system. The basis for the system is simple: Your engine's factory PCV system has several issues. The APR Catch Can System with PCV Plate addresses each one.

The Problems

Firstly, when oil is sucked through the PCV system, it ends up in your intake tract. It’s sucked through your turbo, blown through the intercooler, and forced into the engine. Oil coats the intercooler, hoses, and everything in its path. Not only does this cause a mess, it lowers the effectiveness of the intercooler. More importantly, oil vapors lower your effective octane level, leading to performance robbing, and engine damaging, knock. This means less horsepower, and the possibility of engine damage.

Next, boost pressure and extreme heat is applied directly on the diaphragms within the PCV valve, and directly onto the factory activated charcoal filter solenoid, or N80 valve. The diaphragms can fail over time, causing massive boost leaks and over pressurization of the engine crankcase. The N80 valve can’t hold back the pressure, causing a boost leak into the activated charcoal filter. Boost leaks rob you of power, and can lead to over-spinning of the turbocharger. Pressurization of the crankcase causes oil to force past the piston rings, leading to potentially engine destroying localized pre-ignition points on the crown of the piston. Crankcase pressurization also results in blown seals, such as the infamous rear main seal. Each situation is bad. You’ll end up with less horsepower, possibility of turbocharger failure, and possibility engine and component damage.

Lastly, under racing, or hard-driving, and high G-force conditions, excessive amounts of oil can be forced through the system to be consumed by the engine. This goes beyond light oil and vapor ingestion discussed above. This is excessive amounts that causes plumes of smoke to pour from the exhaust, and engines to fail due to oil starvation. Oil starvation is a serious condition that can cause engine failures in fractions of a second. Often times when any warning of starvation has occurred, it’s already too late.

The Solution

Firstly, the factory PCV is eliminated. A new race-inspired oil separation and drain-back system, or top-plate, is installed. The top plate is diaphragm-free, effectively eliminating the boost activated fail-points on the factory design. The active charcoal filter port remains, but a newly installed check-valve acts as another line of defense before the N80 valve. Internally to the plate, baffles keep oil from spilling out of the system. All oil galleys, including the coarse oil separation galley remain, promoting proper evacuation of crank-case gasses, and proper drain-back of oil into the engine, rather than the catch can.

Next, the APR catch can sits between the plate and the turbo inlet. Crankcase gasses build up within the engine and must be evacuated. The plate prevents coarse oil from easily spilling into the can. Remaining vapors and moisture travel through the can’s multiple layers of internal baffling, collecting in the can while leaving cleaner gasses to escape the system. This leaves your engine happy and clean, promoting more power, engine safety, and engine longevity in even the most demanding of situations!

The top plate, lines, and can all mount cleanly in the engine bay and are made from black-anodized billet-aluminum, with a T304 stainless coarse oil separation galley tube. The can drains easily with the integrated drain valve. All plate mounts are top-side, eliminating the chance of parts coming loose and falling into the cylinder head. High quality braided lines with swivel AN fittings and hose guides are included for a clean and professional looking install. Billet stand-off pegs allow you to raise and retain the engine cover, should you so choose. Precision bracketry makes for an easy, and solid install. Lastly, an optional washer fluid reservoir also allows for usage of the system on vehicles that otherwise would have a washer fluid reservoir blocking the install.

They worked for replacing shelves but I wouldn’t mount them on my wall
Size: 24inch, Color: Walnut
I specifically bought these shelves because of their dimensions. I have a built-in cabinet and when we moved in 6 or so years ago, the previous owners must have taken them with them when they moved. It’s been bothering me the whole time I’ve lived here and wanted to make some but just never found the time to get around to it. I measured them out and these floating shelves were perfect for the dimensions I needed to replace the missing shelves. Would I put these on my wall(s)? Absolutely not unless I corrected the mounting issues. One thing that really stuck out to me was how bad the design was for mounting these shelves. When I took them out of the packaging, the brackets were falling out of the back everywhere. This did not inspire too much confidence that if I hung them up, they would be stable. I’ve had a ton of floating shelves similar to this mounting design, but the arms that the boards slide into on the wall for this particular shelving are thin and flat (while being easily mailable with your hand alone) in comparison to every other one I’ve had being round, or at least decently thick, sometimes with additional screws that you can insert under the board and into the mounting arms for extra stability. Also, any time I’ve ever had to mount a similar floating shelf, it took some finesse and strength to release the mounting arms from the back of the shelf because they fit very snugly. The fact that the mounting brackets were falling out of the back means that they are not snug and prone to be very loose. Another thing that stuck out to me is that the shelves are hollow. Now, for my purposes, this is fine, but again, detracts significantly from the confidence that these would be stable if mounted on the wall and would most likely droop when weight was applied. I also took issue with the fact the boards had no protective covering and were jammed into a box, with the hardware pressing against one of the boards tightly. I just flipped the shelf over to mask the defect from packaging but the side I wanted to use because it had better coloring was the damaged side. Mine did not come with any mounting directions but some common sense would be all you needed to put up something so simple. However, it did not come with a template to mark the wall for spacing, which adds to the difficulty because you have to have precise DIY measurements to slide the boards onto the mounting arms correctly. To be honest, if I were to mount these, I would bypass the shoddy mounting provided and go with some heavy, durable brackets underneath. Overall, these shelves worked for my purposes but I can see how the reviews would be very mixed in terms of mounting and quality. I did get these on a limited time deal and they were priced at approximately $8 per shelf, which was a really good deal to get 4 shelves for that price in comparison to the “normal” price resulting in approximately $11/shelf. I wouldn’t have paid full price for these and would have been highly disappointed had I with the intention to mount them, especially since I would have needed to provide better and more stable mounting hardware. They are lesser quality than others within the same price range and I think you could do much better if your intention is to mount them.

Would purchase again
Size: 48inch, Color: Light Walnut
I was not sure what to expect when I purchased these. I thought maybe they were going to be a fake particle board. But this was a solid wood. Easy to install, no directions were in the box. There was a few chips in the corner of the wood but overall I would purchase again.

Very nice shelves they look great up and were easy to install. Same color shown in picture. They seem very sturdy on the wall and I love the look of them. They are light weight and a good size just a little plunder 40 inches. Good quality for the price. I'll be buying again.
