You do have the new cans that can be updated with the new diffuser. The parts are on the shelf when your ready and can be accessed by the links in the text under the video on youtube.

What a refreshing thread.
Not one post from itguy08 on why catch cans are not needed.
Hope I didn't type to soon.

So I've driven the truck 250 miles [give or take] since installing the diffuser into my full-size UPR can. At that time I also wiped the output hose of the UPR kit dry on the inside.
Drove it normally: city, freeway, and a few short WOT runs in the last few weeks.
The results look good for UPR but alittle confusing to me.

The outlet hose is not dry like I left it. However, the motor-side of the hose has less oil on it than the side of the hose closest to the can. Also, the outlet elbow fitting (the piece that connects to the motor) is much drier.

If we compare just the elbow fittings, then it appears from the photos that this setup is doing an extremely good job catching blow-by. But the wetness of the outlet hose has me scratching my head alittle.

First picture: the inlet elbow from the motor, which is obviously coated with lots of oil, as you can see with the reflection of the sun.
2nd picture: the outlet elbow, which is MUCH drier. There is no big sheen on it like there is on the inlet. It's not perfectly dry though; there is a very light film on it that you can pick up with your finger, so we know that some vapor is pulling through. The film is pretty insignificant though. I did my best to take the photos so that the light would catch the surface inside of the elbows so you can see the difference.

I still need to do this test to the throttle body so I can really see what's going on.


EDIT: To partially answer papatiger's question, I added the picture of what I caught in 250 miles with the UPR extended can w/ the diffuser.

Several drops drip from PCV an hoses. Oil vapor + all other vapor travel through them. How much are you collecting in 500 miles on average? All that gunk isn't in your motor!

How UPR stepped up and made improvements (good well thought out ones at that also!) so quickly is what we should always see, but usually most want to shoot the messenger and silence any data such as this test showed.

I am impressed and look forward to the 2nd stage of the test where I predict we will see the UPR now collecting 90% plus of the mix putting it right up near the top (in the top 10 at least, top 5 will not surprise me).

This helps all, but the attacks from ITguy and engmikes group will continue. Why they have such a vested interest in silencing issues and fixes is beyond me.

And Joe, you can with confidence do the same test with your new improvements against most other cans on the market opening more eyes. Start with the biggest names, Moroso, etc. The goal is not to slam anyone, but to make sure all know what they are buying and installing as one thing the vehicle owners do not have is time to sit back and find out later they installed a product to address an issue and find it really did not.

I just emptied my RX cans today, I have a regular one on my 5.0 and a monster on the eco.after 500 miles I'd say I got 5 oz. out of the 5.0 and after 300 miles about 3 oz.out of the eco, these definitely work,my oil isn't rising on the eco like it used to either,I don't know if it is because of the weather or the can, maybe both. anyway,I'm glad I've got them when I see the crud they collect.fyi

Just a note about how to make your catch can more effective. The more remote and cooler you can keep a catch can, the better it will be able to turn hot vapor/misted oil into a solid form. The mounting location is an important variable to consider that most people are unaware of.

Longer hoses and further away from the engine exhaust or turbos will yield better results. For those looking for the best containment just lengthen your hoses and mount as close to the fender as possible.

Just a quick note.

Joe, does this mean it's not good to mount the long UPR can in the same place as the short UPR can, due to the extension having no choice but to touch the radiator hose? This is how UPR designed it, and it's the only location that the extended UPR can is outfitted to mount in on a 5.0 F150.
My can does get hot in that location but unless I fab up my own hardware to mount it in front of the engine bay like the RX can and buy longer hoses, I have no choice but to keep it there.

Joe@UPR

The vehicle moves a good amount of air in that area. That is why we mounted it there, I was referring more to the cans that sit next to the headers or on top of the engine primarily.
