UPR Catch Can/Oil separator. Does it work?? One of the best preventive maintenance upgrades you can do.

That guy is a rookie with catch cans. I have run them on my gas vehicles for 14 years to be exact. From 2 corvettes, jeeps and 2 different GM 6.2 gas motors. I would not use that can too small and hard to service.

One of the best things about catch cans is if it is properly designed it will catch condensation as well as the oil. This is a picture taken a few years ago when I thought the can was empty (in my driveway). Had been driving it in very cold weather.

Did you even watch the same video? How is that can too small or hard to service? It actually did a good job at removing oil, most cans like the JLT remove oil and condensation - but condensation isn't what matters going through the engine, it's the oil which results in carbon build up.

I'm actually surprised at how well this design gets just oil - is anyone else?? I guess there is also a debate between UPR and JLT about where the catch can should be installed (in the PCV system, not physically) - how does everyone feel about the two designs?

I haven't looked at the JLT so I won't comment on that design... The most common issue with oil pullover occurs through the PCV valve and into the intake on a naturally aspirated engine. The UPR is properly designed into this circuit. Forced induction is potentially a different story, depending on the engine.

You need to do a little more research....

This is the product I have used for almost 10 years. Have been to his shop in Florida and my C7Z06 was the first one he installed a can on. The size of the can absolutely does matter because moisture from condensation and unburned fuel does cause issues. Look at the color of the contents of the picture I posted. In the summer when it is hot the water from condensation is not a issue however the larger the can and when it is located away from the engine will coalesce vapor back into a liquid. Do you have any experience with catch cans? I have hundreds of thousands of miles using them.

I have quite a few pictures but they are all to big to post to the site will have to shrink them. With the cover of the SC of my Z06 off oil was every where BEFORE the catch can IC bricks were covered, car had about 2k on it and after a couple of thousand miles. After the catch can it was dry as a bone!

I don't doubt the catch can you posted is a quality unit which is tailored for performance vehicles - however that is exactly not what a Tremor is. That particular setup is also more focused for performance boosted applications where the arrangement is more critical and since the tune is being pushed a lot more, removing potentially unknown variables such as PCV related oil can be more important, who wants the build up and potentially impacted ignition in a performance engine after all?

However all that matters for a 7.3 NA Tremor is removing the oil. Even removing the oil has limited benefits in the 7.3, carbon build up on the intake valves isn't even a concern since it's port injected. All the catch can is really doing is reducing the slime build up in the intake and I would say some carbon build up in the cylinders over time (which of course to many will be worthwhile). Moisture being burned in a 7.3 simply doesn't matter - it's completely normal. Ever notice water drip out the exhaust? There is this thing called humidity which happens to exist in the air around us.

I've been in the boost game a long time myself and know a thing or two about PCV and catch cans - I've done quite a bit of experimentation as it's tough to get it perfect when boosted (I also own a Twin Turbo 2003 Cobra I've had for a long time now).

For you to say that catch can is necessary and that the UPR is is no good on a Super Duty is pretty funny, it's not a racecar.

 

[Skibum1681]

I could be wrong but I think the OP is looking for a "performance" application, after all his signature states that he has a pro-charged 7.3 Tremor...

 

[NL-Tremor]

Yeah his truck is Procharged and the UPR unit is actually designed with that in mind.

I know it is not a race car. It’s a big fun heavy truck. It’s all personal preference.

Yeah man I don't even mean that to come across negatively, I'm just saying there's a difference in how far you go with things - it's only "race cars" where it makes sense to go to the nth degree with all things as it's justifiable.

In this case I think the UPR unit is more than adequate - that's all I'm trying to get across. I'm still amazed at it's oil separation, I was expecting the yellow oil/water emulsion, to me keeping the water out of this thing is great as for a "daily" vehicle the water can be a problem (it can freeze in cold climates for example). The subaru guys run Crawford units with coolant lines running through the separator to keep it warm when it's freezing.

I am sorry but you are completely in the weeds on this one. I have had may high performance vehicles including this one with a 540 Scott Shaffiroff Race engine built specifically for the bike. My Jeeps were not race cars, the 6,2 liter trucks were not, nor was the Z06 until or the Calloway 2 different vehicles. I got into the motor on the Z06 . You logic is 100% flawed and I have hundreds of thousands of miles on various vehicles and powertrains to prove this out while you do not.

BTW the exhaust example you use just shows that you are not experienced with high performance vehicles or regular vehicles for that matter. All vehicles show condensation in the exhaust system. Sorry but you are in the weeds big time on this one Captain Google. You cannot BS me.

I have the JLT catch can on my truck. It catches a lot of nasty looking stuff that definitely is better to be removed than put back in to the engine. There is about a 1/8 to 1/4 cup of liquid in it when I check it monthly.

 

[stufarmer]

I had a little over 2 tablespoons of Oil in my JTL canister after our trip from Tampa to Grand Junction.
About 2400 miles averaging 75-85 mph. The trip computer says I'm averaging 12.5 mpg.

I completely agree with you.
