Oil Catch Can. Yes or No?

[dtech]

I installed one - I think it's a UPR, dual port. Hasn't caught much of anything in over 10k miles, just a couple of ounces when I emptied it, so I've changed my opinion and would now say it's not needed. Not the easiest item to install so hoping the components hold up over time. Similar experience on my wife's 2013 hyundai turbo, but now that one "catches" a bit more as the car ages and consumes some oil.

My Catch Can …

Might be worthy of a (new) thread Doc, I was told by the owner of UPR (when I went back for the second vacuum line) he felt the crankcase needed venting. You can't deny that it's there but I don't know what affect it has in the operation of the engine or if it is factored into the design. I haven't heard an absolute argument for or against putting a vented cap in.

On topic, in the 28K miles I've driven with my CC I've dumped a lot of nasty looking crud out if mine. Maybe it has to do with climate, fuel and driving habits, but I'm in the camp of those satisfied with the install - as big of a pain that it was. It's never coming out and certainly does no harm as long as you empty it.

I have the mishimoto catch can have had it on for about 3k miles now. Checked it after 500 miles and not a drop. Checked it today and got about 6.5ml. No fuel smell at all. Glad to see its doing its job.

Yeah but only cause I have one on my F150 that I'll transfer over.
It's a high capacity unit and has plastic lines+OEM fittings to prevent hose collapse and leaks.

I'm sure the little ranger will be fine without it, but eh I just want to protect it best I can...

What part # is this? What benefit in using it?

 

[Doc]

CFM Crankcase Breather
It’s function is to remove the positive pressure that can build up in your crankcase as a result of blowby.

There website shows no application specifically for the '19-'21 2.3 Ranger,
only for '2012-2016 EXPLORER ECOBOOST 2.0 & 2.3.'
Do you have knowledge that it fits our trucks?

I am suddenly struck by the similarity in the arguments between installing a catchcan and wearing a mask after vaccination!

This one fits or I guess you can use their “universal”

Since you live in Arizona where it is warm and dry most of the year you shouldn't see much in your CC. I've had the Mishimoto can on for about 40K. I catch almost zero oil/fuel vapor in the warm months and ALOT when it gets cold and snowy in the winter. When I say ALOT I mean I have to empty the can at every refuel. It gets to be a hassle so I'm going to install the drain valve kit they sell so I don't have to unscrew the can....It gets hard to remove when it's cold, even with a little oil lube on the threads. I definitely believe in catch can's on these motors. When I think about how much vapor my engine has captured over time....WOW!

My Catch Can …

Hi @Doc , when you installed that did you change anything else about the system? The reason I ask is because I tried something like that a few years ago, though it was a smaller vent. I had a catch can on the PCV return path but no can on the crankcase/turbo inlet side, so I tried disconnecting the turbo inlet return path, capping off the turbo inlet port, and adding a vent like you show, although a smaller one.

It worked for a a while until I was heading up a long grade toward a mountain pass, when the system threw an error and disabled the turbo, putting me in 'reduced power mode' or something like that. I can only assume that the crankcase pressure was too high. I pulled over, reconnected the normal crankcase path, restarted the engine and everything was OK. After that, I added a second can on the crankcase turbo return path instead of the vent. It seemed like just venting the crankcase wasn't good enough. If this has worked for you, maybe the size of the vent matters and mine was too small?

No I just added it after my 1st Blackstone report with high fuel dilution. It is now less than 0.5 %.

I ran a catch can on my 2019 Ranger pretty much since I bought it new, I emptied it every oil change interval (4k miles for me) and sometimes it had more oil/crap in it then other times, but it always had something. So it obviously makes its way into the intake manifold.

 

[Desertranger19]

Oh I forgot to add, I got the JLT 3.0 kit on my 19, which im trying to install on my 21, anyone have it installed on a 2021 model? I couldnt seem to find the same connections, so Im wondering if something was changed and now wont work for the 21 model.

I've only had my UPR catch can on a few days so I didn't expect anything to come out of it
(or I'd have put a container under it to see how much was in it).
Opened the valve (drain hose comes out at the bottom edge of the air dam) and several ounces of watery oil/oily water came out onto the gravel.

Glad I have the can installed and that stuff isn't going into my intake !
