Nothing in catch can?

[JeebusCripes]

For those that say you don't

need a catch can. Check this . This is after 9,800 miles. That is not inside my intake and all the better.

dang. 2.3 or 2.7? Are you running a tune or is that factory?

Factory, no tune.

@SevenT .... Which Engine? 2.3L or 2.7L?????

This tiny amount of oil over that many miles is NOTHING when you consider that all of it that gets hot or carbonized (near hot engine parts) will be ”washed away” by your port injectors. Therefore your intake and valves will be just as clean with or without your can...IF you had ONLY direct injection, then this would actually be a benefit.

Sorry, 2.7L. Did not read correctly. Engine is original signature.

From all I've heard, these new 2.7 gen 2 Nano's are dual port injected. They have no need for a catch can set up.

Agree to a point in that the 2.7 dual port (unlike the 2.3 direct injection) will inject gas ahead of the intake valve, which will help battle the carbon build up on the back of the valve caused by the crank case gases coming back through the PCV system and into the intake, but the catch can will still "catch" the oil vapors suspended in the air being pushed back through the intake, which in turn will allow for a cleaner combustion and lower emissions.

It works! I guess I just didn't wait long enough to check it. I have 2800 miles on it now and it now has a small pool of oil at the bottom. Strange thing is I expected it to be dirty oil but it is very clean. So, I guess it is working as intended?

I'm just hypothesizing as I'm no scientist or mechanic: could it be a lot of unburnt fuel mixed with oil?

Is that why I get 12 MPGs?

I just checked our UPR catch can on our 2.7L First Edition after about 9k miles. It's definitely doing it's job.

I would also prefer it not mixing with fuel in the cylinder since I pay for 93 octane and getting a tune.

As the engine wears in and the tolerances start to loosen the can will be 50% full every oil change. It’s true that whatever makes it to the intake will be “mostly” washed away by the port injection, but people are ignoring the benefit it has on the pathway before it gets to the intake. For instance, the intercooler, without a catch can some crud is being left behind to eventually accumulate in the intercooler.

Currently at 2,500 miles and some harder use. Starting to see a little bit of oil at the bottom of the can. Must be breaking in!

Alright guys so I installed a UPR catch can and oil breather cap on my 2.7 bronco day 1 with 40 miles. I have 1,600 miles on it so far with some hard use, first oil change performed at 1,000. At no point has the catch can picked up anything. There is a slight oil film inside but nothing more. Catch can is definitely installed correctly. Anyone else have this "issue" or know what could be the cause? The only thing I could think of is the breather cap is allowing the crankcase to breath so well that the catch can doest have enough oil to pick up. There is often oil coated around the cap. Any help is appreciated.

Interesting.... I agree stock 2.7 shouldn't need it but there should be more than a film. I'm leaning towards the breather being an open system.

Good thing is you are a step closer when performance upgrades ore come out n running higher boost.

Do you happen to be saling these through your business?
