JLT or UPR Catch Can Which one, Whats the difference

[SHOinVa]

Greetings All - I've been reading through the forum and I know the question "Should You Use a Catch Can" is not a black and white issue with many different opinions, one person blamed it for destroying his motor. My questions is about which one to use an is the difference worth the money. Correct me if I'm wrong but the JLT ($140) version is just an add on to the PVC valve that creates a low point in the line to collect contaminates. The UPR ($370) version uses the turbo to actually create a vacuum to vent the crank case. Now I tend to believe you get what you pay for but the UPR one is well over twice the price, looks to be a lot harder to install and do you really need to put a vacuum on the crank case. If I was going to the track on a regular basis or creating a lot of boost for extended periods of time I could see the need for the UPR, but my car is just for road trips and playing around on the weekend.
- Ok SHO world an people who actually know what they are talking about, did I get this right and does anyone have any advice or input, As always thanks for all your help and advice and have a great day.

I've been sitting on my McNally kit for a month now looking for time and the cleanest install. This is the odd thing, I have yet to check my intercooler (for a lack of better terms) for oil accumulation. I have a 2013 PP with 40k miles. I've had the pipe off nearest the thermostat when I replaced it, the pipe at the throttle body when I purged the noise maker, and there's not a drop of oil anywhere, not even enough to produce a sheen. Throttle body is crystal clean. When I pulled the factory separator off on the rear rocker cover from what I've been reading I was expecting oil to just pour out but I'd be hard pressed to say I got more than a few drops. This has all been done over the last 90 days. It make's me wonder how prevalent the issue is and what the root cause is. I'm installing mine as a precautionary measure, but it blows my mind how some can be so bad vs what I'm seeing on my car.

Well since no one else has an opinion, my guess is the fact your car has low miles has something to do with it. I would assume you, like me rarely drive it in really cold weather, from my reading that has a lot to do with it. The rest of my guess would be how much time you spend pushing the little silver peddle and how much time you spend creating a lot of boost. Seems most of the people out here who run there cars hard are on meth which seems to keep everything nice and clean. I have no intention on going that far so like you its just a precautionary measure. Anyway that's my guess.

My every day driver, I picked it up on a lease turn in the better part of a year ago so I can't say what the original owner did with it but the Ford Oasis shows he had regular maintenance done at the dealer. I don't drive it like I stole it, but it doesn't get babied. After a lot of reading here and over at Ecoboost I went with the McNally based on catch results posted. Even though my induction pipes are clear, it really doesn't mean oil isn't finding it's way to the valves via the pcv system.

*BUMP*
Greeting everyone, I finally got my tune so I assume I'm making more boost longer, which tells me its time to pull the trigger on a catch can, same questions apply, anyone have any thoughts. Unless someone can give me a reason I'm leading towards the cheaper JLT version, Does anyone out there have any input. Have a great day all.

My JLT 3.0 catches a significant amount during heavier driving. Times like now when I really just knock the cobwebs off everweek or so I don’t see much or any contaminates.

Is there any possibility that these catch cans could cause seals to fail in this engine. I know that the stock PCV system is design to maintain a certain vacuum or pressure within the engine. Has anyone heard of the possibility these could cause to little or too pressure /vacuum within the engine? Just debating if I need one as Ford might balk at warranty for engine seal failures with a modified PCV system. My car is 100% stock.

It seems JLT is actually a local company in my area, I'm giving it a few more days to see if anyone has any input but its half as much an something even I with my limited mechanical ability can install, some of the other ones not so much.

Good question I don't have any input other then FMC is not good with long term thinking, look at the PTU there is no requirement for maintenance and yet I can tell you from experience it needs to have its oil changed. I've heard a few people say catch cans cause problems BUT I have seem far more examples where it kept a lot of oil from from going into the engine.

The jlt 3.0 can be removed without a trace as long as you retain the stock pcv pipe. The other I’m sure can be removed too I just know from experience I can remove mine in a minute or two

Found this statement from LMS about using a catch can. Link is also provided in case you want to read the whole discussion.

If you do not notice any oil in places where it shouldn't be leave the PCV system alone! You can cause serious damage to your engine by altering the crankcase pressures.

"...The fact on the "need" for a catch can is that if your vehicle does not have an oil consumption or build-up issue inside of your intake there is nothing wrong. The best ways to avoid any issues is to use the best fuels available to you in your area, and mod responsibly. Do not buy EBay tuners, use gas from that station that gets fresh fuel once a year or potentially create a vacuum issue inside of your PCV system.".

Adding a catch can can alter pressures to the point of causing a failure. There is no argument about that, regardless the platform. There have been several failures from PCV mods. The easiest way to be alerted to there being an issue is that under normal loads there will be blue smoke that comes from your exhaust. Threads that waiver between multiple issues cause confusion, and ultimately mass panic. That is how this became such a giant topic for discussion.

- Thanks Jeff, you have given me something to think about, BUT I'm not sold just yet, I've seen pictures of some pretty nasty stuff SHO owners poured out of the cans that would have gone into the motor. I do see the point you (LMS) is making, but not all CC are the same the JLT one I'm looking at just creates a low spot, so pressure should stay about the same I would think. Lets circle back around for a moment, If I don't have one will the stuff being run through my motor give me problems over time or will it just burn off as long as I use good gas an keep my foot in it from time to time.

If your engine is performing as designed the buildup of carbon should be minimal. If you are getting a lot of blow by under boost then you will probably develop a carbon issue but I think LMS is saying that is a symptom of the blow by issue or some other cause which should not be happening. I think the tunes that increase boost are large part of the need for the catch cans. The reason the F-150 has a bigger problem with this is because they run higher boost pressures from the factory. I know there are SHO's with 150k that have never had a carbon buildup issue. If you need to add oil between oil changes or see a noticeable change in the oil level on your dipstick then you might benefit from a catch can. My car does not appear to use a drop of oil in the 5k interval. At least it is not apparent from the dipstick. I am running fully stock.
