Getting ready to install an oil catch can on a 2021 Expedition but the directions are telling me in freezing temps to leave the PCV system intact. Has anyone had any issues in below freezing temperatures such as freeze up of the crank vent system? Just wondering if I should wait until the spring to install this and keep the factory lines for the winter time.
Oil Catch Can in Cold Climates

Cold weather will create a ton of condensation. The can will fill up with a water/oil mix that will be predominantly water (looks like chocolate milk), and will require frequent dumping. Most people won’t religiously monitor the can and this may lead to the mixture being ingested through the intake, when the can becomes overfilled. This is the scenario the directions are trying to have people avoid, with their warning about cold weather.
Checking weekly should be fine. When I had one on my previous vehicle I’d check it every time I stopped to fill up. The warm crank case vapors will quickly melt anything that may freeze in the can, I wouldn’t worry too much about use in cold climates.
I don’t have one installed on my current expedition due to the use of the port and direct injection system. Some fuel washing of the valves under low loads is occurring with the port injection system. You’ll find a wide range of opinions on the cans here on the forums. I’m of the opinion they don’t hurt to have if you want to install one.
What brand?
That kit looks terrible. It says braided lines, and non of the lines pictured are braided. Those fittings also look terrible on the Amazon listings. Looks like they did a cheap copy of the J&L kit. The J&L kit would have been SO much better. Sorry, just being honest.
Take some pictures when you get it installed, and lets see it.

Thanks for your input. Any experience with Team RXP twin can systems or have you heaard anything either way about this product? I put this sytem on my 2020 expedition. I think it works OK but if you installed it according to the instructions, it was very difficult to drain the cans because of space constraints. I added some additonal hoses and ball valves that are located in the front wheel well to make it much easier to drain the cans.
Also, how often do you normally have to drain these catch cans?

Catch cans are a MUST on turbo engines
Actually, you could take it a step further. Anything with Direct Injection, even if it also has Port Injection, because Direct Injection is the primary running mode.
Where did you add the additional lines, just to the drains on the cans?Thanks for your input. Any experience with Team RXP twin can systems or have you heaard anything either way about this product?

RXP's kit is a good kit. It is in my opinion overkill. The J&L OSC(JLT) kit is a 1/4 of the price and catches 95%+ of what the dual can setups catch.
RXP's mounting location for the cans, as you discovered is not the best. It can get in the way of some aftermarket intakes, and also a pain to drain, but is tucked and out of the way.
No, I do not work for JLT, or have any direct affiliation with them, just have used many of their kits, and they are great bang for the buck, and do the job.

Question for you since you have a lot of experience with these. Realistically how often do you need to clean the screen on this catch can? I feel like the J&L recommendation was like every six months but it required it to be removed to do it. That’s a pain IMO. Appreciate the insight.
I typically do them once a year, but it is more dependent on miles and season than time window. Removing it takes 5 minutes on a bad day if you are slightly handy. Not hard at all.

Hm. I’m new to catch cans. Installed one in my 22 expedition this past spring. Great info, as I was not away about checking on it more frequently in colder weather. Went and looked at it today and saw some of that coffee ish color for the first time. Also, what’s this cleaning of the screen you speak of? I must have missed that tidbit during my readings. Any insight or literature on how to do that?

It’s up in the top when you unscrew your can. It’s a gold screen that the stuff is filtered through. When I got my can there was a QR code to a video that I can’t find right now. But here’s the bottom page of the instructions talking about it. I think the video said use carb cleaner or degreaser.

Theres a video on the j and l site. Basically take it off and spray brake cleaner in it, let dry a few minutes and reinstall. I havent done mine yet, but should soon. I empty maybe a third way full can every three thousand or so miles.

LokiWolf. Thanks so much for your response. Most of us DIY hacks really appreciate your wisdom on this platform.
Regarding my drain lines for my RXP dual cannister setup, I dropped one line from each of the two cannisters and brought them into the driver side front wheel well and put on two ball valves. I think they were 3/8". I had to adjust one of the ball valves a little higher after initial install due to a slight wheel rub. Makes it real easy to drain the stuff in the cans. I just do it with each oil change. Without this setup, it is a royal PITA to drain the cannisters the way they are set up to be mounted by the manufactuerer.
