If you live in Canada and are thinking about buying one of these I wouldn't. I bought one from UPR, nice can and all, but if the temperatures are even a little bit below 0C (32 F) you will have problems with freezing. I had it installed on my 5.0 with the added diffuzer, and within only about 100 km of driving it froze up solid. It was only -7C outside, and the diffuser was so frozen there was no chance of anything getting through. Engine temperature is not enough to thaw it, and even if it was do you you really want to run your engine for a short time with it plugged? Luckily i noticed my oil pressure gauge shooting up, and i took it off before anything blew.


I talked to UPR about it, and they told me that water is bad for the engine and it's doing it's job so they wouldn't return it... but really water in that ammount won't do anythign to your engine as there's tons of water in the air naturally. The guy also told me to pour some boiling water down it in the morning.. but who the hell wants to do that to their truck every morning... My advice, if you drive a 5.0, the gas will do a good enough job at keeping your valves clean, and you do not need the added hassle of one of these cans. Don't waste your money. As for the direct injected eco-boosters.. i still wouldn't do it unless you park your truck inside all the time.. but that defeats the purpose of a truck.. I would probably not buy one for that engine either.

Plugged up? That's not really possible, the lines and fittings are never filled up with any liquid at any time. Hot vapor passes through constantly and any residue that might freeze isn't enough to block the lines or fittings. Once the vehicle is running and reaches normal operating temps the hot vapor would thaw the contents. AT NO point would anything be frozen and blocked. We have been selling as a competitor of UPR's for years and while we have never had this reported. We also know UPR gives much better service than that, I can't imagine them refusing to take their product back. Not in a situation like this so LAYTUNES, I'm not buying the story. I'd like to hear from anyone that can confirm this story. This sounds like a disgruntled competitor or ex-employee, fill in the blank.

Well it is possible because it happened to me, I guess i should have taken pictures but i already pulled everything off the truck and thawed it out. I had the optional diffuser installed, and the outlet features a plate with a bunch of holes drilled in it, all but one of those holes was frozen shut when i took it off and inspected it. I had it mounted the same way that the guy that started this tread did (on the outside of the rad). I pulled it off as soon as i got home from about a 100 km highway run, and that was the situation. There was just too much water being condensed for the oil to keep it liquid.


As the oil/water vapour moves through, it condenses and freezes on the cold metal eventually blocking it. The highway speed and mounting position may have played a factor in it, so a heater or insulator might work, but I installed it as per the instructions in the kit. I guess the vapours aren't hot enough to deal with the onslaught of a mild canadian winter.


I explained it to the guy at UPR, and he basically said that he can't return it because it's been used, which I understand. I'm not an employee or a competitor, just a little dissappointed that I wasted 150 bucks on something that didn't work for me. (which is like 230 bucks for us canadians). I might try installing it inside the engine bay, but when i leave my truck outside in -20C all winter i don't know if i would trust it.

It usually gets up above freezing in my neck of the woods but I recall Ford used heated PCV valves up north to prevent its freeze up so kind of dump to not think a can wouldn't freeze up there too but the can has acids in it also changing the ph of the moisture in it.

Reason is likely that you bought the small can and not the mega size. In freezing temp with the mega I need to drain once a week. And I'm in Canada. I've had the water layer freeze in the can however the diffuser section will only freeze if you are not draining it.

Laytunes

That's a good point about the mega can, if the level gets to high it might be able to splash up onto the diffuser and freeze. I might try mounting it behind the rad to see if it stays warmer, and empty it daily and see what happens. A shorter hose too might also help keep the system warmer as a whole. It's cold here this week so I'll report back with findings.

Plug a new hose in back to stock if u find frost until spring. It's not that expensive an drill ur tiny hole in ur cac

I have come to the conclusion after over 2 years of experience with the mess in the can that it consists of nasty liquid stuff and clumps of nastier greasy messy stuff. Take out the oil and there would only be water. The only water stuff would remove itself in a much more complete way from the CAC and probably not even be noticed if not for the oil nasty clumping clugg hanging onto it. Thus this is where the can and condensing it is important. It never gets to the CAC and the water doesn't build up in it.

I have had mine for about 2 or three (5,000 mi) oil changes now. It only has oil in it. The oil looks like what I drain from the engine but there are no clumps and no water. I live in a fairly dry climate and mostly take trips long enough to fully warm the engine. I am glad not to have the oil in the intake.

I live in the south which is much warmer most of the times. This past week and today we are in the 70's which is unusual. I have a small catch can from SilverHorse Racing which is basically the same as a JLT. I also installed a oscillating tube screen from JLT into the SHR can. Mine is mounted in line using the stock PCV tube that I modified. Never had any issues with mine, but I will check and dump it more in the cold weather now since the warnings. I just don't see the need for running such long hoses on a N/A 5.0, but if you want the large can to drain it makes sense. My setup is the same exact factory tube with the small can installed in line where the engine bay heat is at.
