The "Catch Can" Explained - By Elite Engineering

It's extremely critical to keep the vacuum stong and airspeed up so be sure to have the least restrictive setup possible on the dirty line of the PCV system. This is where the vacuum is utilized to help the rings seal and evacuate crankcase pressure which is very similar to a vacuum pump. So basically, you will be introducing a reduced flow/small line system where you should have something that flows the same as factory or better. I would really be looking for a much higher flow unit to go in the PCV line so you do not lose the benefits of the strong vacuum signal from the intake manifold.

This is the reason we build UPR Plug n Play™ Catch Cans with OEM and larger UPR braided hoses and UPR plug n play™ fittings so they always flow the same or more than the existing line/setup. It's very important to keep your PCV system flowing smooth and maintain vacuum at all times as any snake down in line is detrimental to the efficiency of the PCV and the overall performance and mpg of your vehicle. The benefits of the oil you catch will be negated by the lack of vacuum and any restriction smaller lines and traps can cause.

You have the right idea, just need to get some serious flow parts to accomplish oil control while maintaining the same or better vacuum.

Hope this helps.

This shouldn't be an issue, if it is, please let us know.

UPR and Elite, do either of you have plug and play kits for aftermarket CAI's? I drive a 2016 Sierra Denali with the 6.2L V8 and have the aFe Power Momentum GT CAI so the lines to/from the catch can will be different lengths vs the stock air set-up. Looking for the best deal between the two of you, thanks!

yes your right i will have to tap into the pcv next, I am amaized at how much oil vapor i'm condensing off the valve cover ports. all this oil vapor has got to be causing issues with the air flow sensor behind the air filter, on top of disrupting airflow over the intake valves

found another cyclone oil trap from a C70 Honda Passport $8 from ebay , uses smaller hose fittings , should fit right into the pcv line

Why take the risk.

If you want a catch can buy one made for the truck.

GEEEZ!

Thanks for your message. Shoot us an email at [email protected] or [email protected], and we can definitely help you out. My daily driver is a 2016 GMC Sierra 62L with an aftermarket CAI, so I'm very familiar with your set-up.

its only $8, and cyclone separator design is superior to the current designs put out there by aftermarket shops.. why else dose the Auto industry use a centrafugal system compared to the aftermarket's blowing gases into a Can design ? its not proper filtration. Automotive companies put way more engineering and research time into a rugged system. the cyclone, filters better, and the higher the flow speed of the PCV the cleaner the output gases v.s. a high flowing aftermarket design will get a lot of blow by past the filter can..

I don't think anyone is trying to rag on you for what you are trying to do. We are voicing our opinions in a bid to help you from experimenting on your truck. If you end up with over pressurization or diminished flow you risk damage to your engine. What's going to happen if you install a part designed for a Honda, Audi or BMW and blow out your rear main seal or have some other oil related issue? If we didn't say anything it would be like really uncool. I will never tell you what to do with your truck, just like I never tell people how to parent their children (although that's tough at times lol) so I truly hope it works for you, I really do.

You should experiment on a loaner from the dealership...not that I have any experience on that or anything...just saying that's all...muhahahha.

IMO:

if it works go for it.
If it doesn't work as intended but looks cool go for it.
If it looks like @$$ and doesn't work...well I hope that Honda oil trap works.
I don't tell people how to parent their children either, keep my mouth completely shut...as I parent their children for them

.. so I finally got the chance to install the single port UPR plug n play kit on my truck today. This is my honest impression of the installation:

-- Shipping was fast and arrived well packaged

-- instructions were supplied for 18-19 MustangGT Wipple charger w/CSS application.. not much help for a 18 Silverado 5.3. Fortunately with the help of this forum and YouTube the installation instructions were obtained.

-- mounting bolts on top of the can are located directly underneath the middle dirty port (I'm sure there is a logical reason for this.. they just could've been located elsewhere for my installation) which made accessing the bolts here difficult; in fact I ended up losing a washer trying to work around the port.

-- the quick connect fittings and hoses are AWESOME.. (large reason I was swayed by the UPR can). The 90 fittings are easy on/off like OEM with a single press point. The straight fittings are much more difficult to remove as they have double press points and these end up on the motor end where access is limited.. but they are still fantastic.

-- both hoses were routed alongside each other then under my engine cover.. there is just enough clearance without modifying the cover; however I will add some split loom at this point for added protection. The dirty line then runs along the intake following the original path hidden by the cover.

The final plug n play install ended up looking much cleaner then I had anticipated and I am happy with the result; however I will still probably end up relocating the can to the front corner of the engine to free up the area around the oil fill and dipstick in the spring when the weather warms up.

I have to say that's one of the BEST looking engine bays I've seen, from the white engine cover with the Storm Trooper is a very COOL look. Thank you for the honest and flattering review of the UPR Catch Can. I've been working hard on continually updating the UPR Plug n Play™ Catch Can Fittings and love to hear the feedback as it helps me to improve our products and ease of installation. No Bias here but I love how clean the UPR Catch Can looks with the UPR Braided Hoses and Plug n Play™ Fittings that all flow together like a factory product or NICER.

Feel free to hit me up if you come up with a good alternative mounting location for the catch can.

Thank you, Joe@UPR

Joe, sent you a message a couple days ago to place an order. I'd like to install asap because I have a couple long road trips coming up starting next weekend. My whole top end is brand new due to warranty work so I'm trying to get ahead of any oil build up before too long. If you could get back to me that would be appreciated. Thanks!

Agreed, the nicest engine bays I've seen that looks like it came from the factory. Very tastefully done. Thanks to @STRMTRPR and @stanz792 too for answering my questions about the engine cover. Especially nice for the non-biased review.

I am going to reinstall mine tomorrow using this location. Using both bolts should give added stability using my new bracket I had made. Old bracket is on the left, new one is much stronger.

Dawned on me I never showed the actual bracket RXP made off my drawings...the small one is what I originally received and it works but I wanted something more so they did this for me...no charge or shipping.

Nice service! I think it was mutually beneficial. You got what you needed and now they have a template for those who want the same set up as yours!

And thank you for posting up that vid I was describing, and also describing it 100% better!

I evidently wasn't clear enough but thought I made it pretty clear (see above posts quoted) that I DID NOT MAKE the bracket, I HAD IT MADE. The company I purchased my Catch Can setup from RXP made me this bracket BASED OFF OF MY MEASURMENTS AND DRAWINGS. They did this and shipped it overnight FREE OF CHARGE. They now have 10 of these brackets in stock for anyone that needs them, permission was given for them to use my design.
