I am new to the Forum and have a 2017 Sierra with 12K on it. I understand the principle behind the catch can and it makes sense. The problem I have is that there is a lack of evidence that it actually does what it says it will do. I have no doubt it removes water and oil but does it actually reduce the carbon build up on your valves? With the amount of money involved in selling an promoting these things I can believe that someone has not performed any type of controlled scientific study. It would be simple for a company with a fleet of vehicles to take a group on new trucks and have some with and without catch cans. After a certain amount of time or mileage you look at the valves and scientifically measure the amount of carbon on the valves. I have not been able to find such a study. does anyone know of the existence of one? Alternatively, does anyone on the forum have a GDI truck with high mileage that does not have any carbon fouling problems? How are you managing you maintenance? I have no problems installing a catch can but I would like some actual proof that it does what it says it does.

Wondering if anyone has done a pcv delete and run a breather style setup on an l83/l86 engine? Seen it done on older ls stuff and guys talk about a much smoother idle. Recently had a cam swap done and looking to keep intake and valves clean lol.

Finally broke down and bought an Elite Engineering catch can. After some research, I got over the worries of installing one and warranty issues. For GDI engines I think these are a must have. I would rate my engine as ‘severe duty’ for this application as my commute is very short, 3 miles to a Park & Ride to catch a bus. I live in MN so it’s cold in the winter, most days the engine does not fully warm up. I took pics of the back side of the throttle body, not filthy, but dirtier than I expected. I cleaned it up and plan to do again at every other oil change. The intake was wet with oil/moisture, looks like a lot, but I’d guess it’s about a tablespoon or 2. With the 6.2 the PCV vents on the front side, covienent for cleaning purposes, would expect it to be somewhat cleaner further back in the intake. I did not do a clean side separator as I don’t do WOT much, might regret it later, but intake tubes were clean and dry so should be good there. I re-used the GM PCV connectors, ordered a replacement PCV vent hose in case I need to go back to OEM. Looks sharp and I have an east swap solution. While I was there installed an AirRaid Jr kit, I like the flow better with filter and intake tube. It’s almost worth it to keep the oil change guys from always showing you your ‘dirty air filter’ Overall easy install and a fun Saturday project. I highly recommend a catch can for any GDI engines, eventually the valves will get dirty and need to be cleaned, I don’t think a catch can will eliminated this, but I think it will makes those cleanings fewer and father bewtween!

I just bought a 2017 GMC SLT with the 6.2L and 8 Spd. It had 8700 miles on it. It will idle a little rough at idle momentarily. I only run premium gas, is that normal for the 6.2L? I've installed a Magnaflow 12909 muffler w/o flapper valve and an AFM Momentum CAI. Also, since I've had it, it has a tick that is heard when your standing next to it, or in a drive thru with the window down. Is that normal? After reading on here I'm worried about the afm lifters causing it. I plan on getting a Hypertec programmer so I can change the afm to 70mph and adjust the shifting so it's less clunky. I also will be installing an Elite Engineering EX-2 catch can kit. Will these additions help with the common afm issues? To make it more reliable in the long run? Anyone with experience or knowledge please educate me on this, thank you

Just got a new 2018 Sierra with more bells and whistles than I've ever seen in a truck before. Sure learning a lot on these forums. The catch can thing has my interest, I never even knew that was a problem, never had a direct injection vehicle before. I'm looking under the hood on this thing and although it is difficult to see much it looks like there are two PCV valves, assuming that's what I think I'm seeing. They are right up front of the engine, one each side, with short tubes going into the intake air plenum. See attached photo of the front left side of the engine. So question #1, are two PCVs what I am seeing? Question #2, if so then I need either two catch cans, or one that does double duty, right? I'm a little confident that the answers to my questions will be yes (still appreciate confirmation though) and if so this will be a plumbing nightmare. This truck has the eAssist which means the only open space for a can is the front left corner where the battery used to be, on eAssist it's up in the back right corner of the engine bay. And, there is no room at all left in that part of the engine bay, it is packed. So I guess question #3 is, anyone come up with a creative way of solving this problem, besides hoses all across the top of the engine? Thanks in advance for responses.

I have an Elite standard catch can for sale, black in color. Need new hoses but has the L bracket. $100 plus shipping.

Hope you all like tutorials! Shot these over the weekend. Enjoy!

I have an Elite E2-X setup that I plan to install this weekend. I just went through a 120+ page thread on this site about catch cans and early on some claimed that if mounted to the brake booster location it caused a vibration in the pedals. Is this still an issue?

I have had the Elite Engineering E2 Catch Can on my 2014 Silverado for about 8100 miles and just performed my first oil change since it was installed. (Don't worry, I use Mobil 1 Annual Protection). Shocked is an understatement of my reaction when I discovered how much oil my truck is burning. After seeing how much was captured by the Catch Can, I am very glad I decided to install one. I have run a catch can in my Camaro for several years and it captured far less oil between changes so I was very surprised with how much was captured this time. After doing this first check - up on the catch can, I now plan to check the can much more frequently (every 2,000 miles or so) to see how much is being captured. I will be uploading some additional follow up reviews on the catch can and how it is performing. Overall, I am completely satisfied with my purchase and will be purchasing from Elite Engineering again. Note that this engine is shared among many GM platforms such as the Silverado, Sierra, Yukon, Suburban, Tahoe, Express, etc.

The Sundae Drive does an in-depth video showing how to install an oil catch can for a 2014 Silverado 5.3L. What are the benefits of an oil catch can? Well if you visit the follwing sites you can read all about the benefits and importance of running an oil catch can. Catch cans are NOT ONLY for turbo/supercharger applications. They can be very beneficial for people with naturally aspirated setups. https://www.redline-motorworks.com/bl... http://oilcatchcan.com/oil-catch-can-... Purpose of your Stock PCV System: The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase and to alleviate crankcase pressure which could cause oil leaks or seal damage. The PCV system routes crankcase fumes into the intake manifold where they can be burned to eliminate harmful emissions into the atmosphere. The PCV valve controls the amount of crankcase flow volume depending on the engine's load. With large throttle openings (high engine loads), the more blow-by gases are produced, and the more the PCV system flows oil vapor into the intake manifold. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. This leakage is often referred to a "blow-by" or leakage past the pistons. Some of the oil mist and other products settle along the engine intake and over time form a "gunk". Our oil catch can collect the oil mist and condensed the fuel vapors while allowing "cleaner" gasses to pass back into the intake manifold.

Been a member here for a while when I had my '13 Sierra but spent most of my time on a different forum. Due to a lifter/ cam issue, I now have a 2016 Canyon SLE and I think I'll make this my new home! It's weird going from full size to the Canyon but it's comfortable, rides nice, and moves out pretty well, and I'm looking forward to some better mileage. Not planning on too many mods (famous last words), mainly a catch can if needed (gotta research that), and possibly a tuner (I doubt my DiabloSport will work on this one). And I'm anxious to find all the home grown "how to's" from the guys here who've already paved the way......

Anyone put a catch can on a Buick Enclave, Acadia, Traverse? I am looking for install pictures if anyone has any.
