To Catch a Catch Can

[Revolution_322]

Based upon what? Sure seems like the 3.6L dumps a fair amount of oil into the intake based upon the photos others have posted here.

2 words *port injection*

I get what you are saying that DI engines do not have valve backwash like a port injected engine does and that washes the oil away. However, does that prevent the carbon buildup in the chamber from the oil being sent there by the PCV system and subsequently being washed into the chamber and burned?

I am not sure, but speaking only for myself, I would not want the ounces of oil that I have seen in the photos posted here of catch cans to be dumped into the cylinders, but that is just me.

I just installed my catch can today. Jeep has 730 miles on it and I could see some oil at both ends of the PCV tube. For the $70 I paid for the parts and the hour to install I think its a good thing especially since this is the first brand new vehicle I have ever owned.

Yes. A couple highway entrance ramps at full throttle will likely clean all oil deposits from egr and pcv . DI a complete diff story. Thats why most DI engines were re designed to include both port and direct. Sadly the fca motor does not.

The 2.0 appears to not need a catch can and seems to have minimal blow-by when compared to a 3.6. It probably has to do with the SN plus oil requirement.

Here's the contents of a 2.0's catch can after 7,000 miles: https://www.jlwranglerforums.com/fo...2-0t-catch-can-kit.27322/page-24#post-1004586

Wanted to give everyone some quick reading and a smile for the day.

What is the real benefit of a Catch Can and is it a sound investment? Think about this for a second before you post anything trying to
argue the point below, please.

Question: Would you add a single injector or line to your intake that contains oil mist/vapor to inject oil while you drive for any reason?

Answer: Absolutely Not, as it will degrade the octane and overall efficiency. Reducing MPG and Engine Efficiency.

Actual reasons vehicles don't come with catch cans from the manufacturer.

1. It adds additional cost to vehicle production. (MONEY)

2. People consider them to be messy and non-functional. (TURN-OFF)

3 People are lazy by nature and a catch can is considered an inconvenience. (TURN-OFF)

4. The Assumption the PCV system is ok because the manufacturer designed it that way. (MISCONCEPTION)

These are just a few as there are too many to list and I just want to get the point across that you can go without a catch can if you choose
at the expense of Reduced MPG, Reduced Performance, and Reduced Throttle Response. When you install a properly designed catch
can that controls oil you will absolutely experience all the benefits I mention.

As a manufacturer and I've been asked this thousands of times over the years and most of the smaller catch cans and ebay style catch
cans do not give you much of a real benefit as they let more oil escape than they catch generally. The catch cans that use small bronze
air compressor filters, honeycomb filters, or just a flat screen that run across the chamber minimal oil and are deceptive.

It's the smaller ineffective catch cans that give catch cans a bad name in general. Even many of the Big Name manufacturers use the
style filters and designs that are what does not allow the industry to see the true benefits of properly designed catch cans. Just see what
filter types manufacturers use and you will be able to figure out what are effective and what are ineffective catch can designs.

I'm only sharing this to be clear that catch can are beneficial and give good results over time in both MPG and Overall Performance that
a properly designed catch can returns. The newer the vehicle the stronger the vacuum source to the PCV and this results in better ring
seal, on the negative side it pulls a lot of oil out of the crankcase and that is why catch cans are becoming more desirable.

I fully respect anyone's opinion as it is their opinion. I'm not here to argue or debate back and forth about the reality of what catch cans do.
I just wanted to share information on facts and results we have collected over the last 15yrs of watching the evolution of the PCV system
and tricks manufacturers use to improve MPG and at the same time increase oil ingestion. How can a part that costs the same as a simple
cosmetic mod be a bad investment as it returns the investment for the life of the vehicle?

The biggest indicator is the tune up lasts forever and plugs do not get fouled or oiled up. As with a catch can the plugs perform properly
for many years without any problems. I have to say for performance guys and engine builders this is a great sign ove efficiency.

We're continually improving our products to improve oil control and engine performance as modern day engines evolve.

Joe

Joe,
Here's my question, I'm ready to purchase your catch can, what is the benefit of adding the one-way breather and do I need it? Secondly, I noticed that your catch cans are available on Amazon, are these legitimate items that are coming from your company? Thank you, waiting for your reply so I can place my order.
R/S,
Mark

Mark,

You are much better off buying direct from the UPRproducts.com website.

https://uprproducts.com/18-20-jeep-wrangler-jl-3-6-billet-oil-catch-can/

As far as the UPR One Way Breather it is very beneficial as it helps reduce oil pushing through the system by allowing
positive crankcase pressure be released as the engine produces it. It reduces the amount of oil forced through the
PCV and most importantly helps draw in fresh air faster by releasing th air in the crankcase making it easier to draw
in the fresh air. The fresh air also allows the engine to operate cooler by releasing the hot air instead of recycling it
like the system does without the UPR One Way Breather.

We are working on a new oil cap for the 2020 JEEP Wrangler as they changed the cap again.

Joe,
Thank you for the explanation. I have a 2020 Wrangler, what has been changed with the oil cap, does it impact me buying a catch can now? Should I wait?

Hi Joe:

I bought your can and I had a serious issue with it. It loose one ofthe two inside filter screws. When I reintroduced the oil cached into the engine, I introduced without control also this screw...
So I recommend to your company to fix these two screws with some glue, jut to avoid this kind of.issue.

The first line of the instructions states to not reintroduce the oil caught in the can back into the engine. Just curious why that is being done?

So you'd rather the PCV vent on to the ground like in older cars/trucks?

 

[joe@upr]

A Catch can is vital and should always be incorporated if you want the absolute best performance and longevity from your engine. If you vent the PCV at any point you completely rob the engine of the benefits of having a closed system that creates vacuum to evacuate the crankcase. No vehicle should vent to the atmosphere and especially not to the ground or anywhere creating a mess degrading our environment.

The PCV function is very beneficial when properly addressed. The PCV should always be protected from being able to ingest oil. Ingesting oil has a negative effect on all fuel types from regular to premium and should never be left unprotected. The majority of people just take it for granted and never get to experience the benefits of a vehicle that runs great all the time.

(NEVER RETURN COLLECTED OIL BACK INTO THE ENGINE)

The two small screws are gently tightened as they are designed for the customer to be able to remove so they can install the lower portion of the diffuser on the dirty/pcv side of the catch can. Also, the collected contents contains fuel and oil and should not be returned as the fuel that gets into the crankcase during operation will evaporate much faster and you never want to return oil with room temperature gasoline as it can reduce lubrication of the internals during startup and it only takes one time to scar or cause premature wear on bearing surfaces.

So please remember that its never worth it to try and reuse oil from your catch can after it has sat in the can over time. If the vehicle has a system design to recirculate the contents daily and when the engine is at temperature that would be a different story and considerable. Otherwise dump that few ounces of oil collected and just add fresh as the fresh is always better to top off your existing oil with.

UPR Catch Can, Breather Tank, and Check Valve information

1. UPR Catch Can Maintenance
Check your catch can every 500 miles for the first few oil changes to get
to know your vehicles Oil consumption.
Never return collected oil back into the engine.

2. O-ring Protection / Tightening Catch Can
Do not over tighten your Catch Can as it can stretch or tear the O-ring or
even ruin the threads and seize your catch can shut. Extreme weather
conditions and or handling can also damage O-rings.
Replacements can be purchased at UPRproducts.com

3. Check Valve Operation
Check Valves always face away from the catch can. Once Check Valves
are opened or taken apart this will break the seal and potentially lose parts.

4. Plug n Play™ Fitting Protection > Female Fittings <
To R&R UPR plug and play fittings keep them parallel to the Male fitting to
avoid damaging internal O-rings. Push/Squeeze to remove, depending on
style. Clips are not removable and will need to be replaced if taken apart.
Replacements can be purchased at UPRproducts.com

5. Catch Can Fitting Maintenance > Male Fittings <
You will need to put a rubber hose over the fitting to protect them and grip
them with a pliers. Use Teflon tape when installing to seal threads.
Replacements can be purchased from UPR.

6. Weather conditions
Cold weather maintenance, always drain contents after driving to avoid
freezing overnight. You can pour hot water into the catch can to unfreeze contents

7. Catch Can Contents
Catch Cans are plumbed into the PCV line allowing Catch Can contents to be
smelled through the intake tube/airbox. Always check all connections are secure.
An oil/fuel smell is normal if you don’t empty your catch can daily.

8. Catch Can Flow Direction
The dirty line from PCV goes to the IN fitting. The clean line to the intake goes to
the OUT fitting. The IN is Top Center of all top fitting cans. The OUT is the silver
tip on all side mount cans.
5038 catch cans with Multi-Level diffuser run the lower chamber on PCV side.
You can easily switch the lower chamber of the diffuser to either side by R&R
the two screws and tightening.

9. Catch Can Fittings
All fittings should always have Teflon or thread sealer whenever needed.
Permatex Thread Sealant Recommended
