Oil Catch Can. Yes or No?

[Floyd]

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 !

Glad you're glad,
Here another great product which works wonders...

No really!... read this along with thousands of testimonials!

Made from the oil of the Chinese water snake, which is rich in the omega-3 acids that help reduce inflammation, snake oil in its original form really was effective , especially when used to treat arthritis and bursitis . The workers would rub the oil, used for centuries in China, on their joints after a long hard day at work.

Apparently , ( like a catchcan) if you use it for centuries it will really help a lot!

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!

I have the same experience, also added the drain. I also installed a brass shut off valve about six inches from the catch can and the one included in the kit at the end of the drain hose. We'll worth adding the drain kit.

I may be repeating myself but the second vacuum source purpose was vague even though I jumped on it as soon as it was added. The standard catch can designs basically just operate within the factory system and rely on vacuum created by the PCV system... and I see those aware of an overall positive pressure present at the top of the engine installing breathers.

UPR calls the add in kit the Wide Open Throttle option - the vacuum provided by the intake stream of the engine. It would suggest that diverts some of the pressure build up in the PVC loop?

I've seen a few catch cans with breathers on them- not sure how that functions and I can image could throw codes here. I haven't read anyone saying they've had that issue with the breather or the WOT option.

I'm just speculating there might be some subtle advantage to that. I can't say I've noticed.

Yes

Like it or not, it's on mine now and never to be removed. The trauma of the install is fading and I "can" confirm it definitely does catch stuff, mostly in the colder months. I save it up and use it as starter fluid for bonfires.

My thoughts are I would rather have it in place and maybe avoid the problems some people have with buildup in some DI engines. Do they work as claimed or not? Nobody knows with ?% certainty, and to claim otherwise is a reflection of personal biases and fanboy emotion.

Your truck. Your $. Your choice.

Problem is, if "nobody knows whether it works, then by extension, "nobody knows" whether it is harmful.
Fact is, Not even the absolute best in any field can be 100% certain about much, but there are those who combine knowledge and good judgement to produce the best answer most of the time..
You can try and learn enough to make that decision yourself or you can find a source you trust and take his advice. (or a little of both)

I.E...Do you use pure nitrogen in your tires? I scoff at it... but it can't really hurt right?
I listened to all sides, added in my experience, and settled on a compromise blend ....

About 78% nitrogen, 21% oxygen and about 1% trace gasses.
Hey its not 100% nitrogen, but I'm (nearly) 100% positive that it is a better choice than pure hydrogen or a blend of acetylene and oxygen!

I added a little Canadian pine scent to the nitrogen blend and it really perked up the handling characteristics. ?

All I'm saying is there is no proof it works or doesn't. If people want to spend their money on it, who are you or anyone else to decide if it's a waste of money? If you want to place your undying faith and trust in Ford engineers and bean counters that's your choice.

I was going to use one, and purchased the excellent dual-vacuum UPR catch can system with extension. But, it turns out in california it's illegal to install, and the vehicle won't pass smog.

So, I was never able to install it. If anyone wants to buy it for less than new cost -- it's unused/brand new in original unopened packaging-- let me know. At some point I'll also post in a For Sale thread...

It is not entirely clear how you arrived at that understanding of my thought process.
My experience and yours are of course divergent, but we have both had the same information available on the catchcan issue, and came different conclusions.

I am satisfied with the engineering in the 2.3L EcoBoost engine or I would not have bought it.
The same was true with the controversies involved with other engines I have owned in the past.

Remember the coking on the Lima 2.3L SVT Turbocharger?
Remember piston "scuffing" in the Pinto Lima engine?
Remember Timing chain design complaints on the OHC 4.0L?
With proper care, I had complete reliability and zero issues with all three .


If the EcoBoost fails in ten years, I will repair it to stock specs( providing I am still around and able to drive.) Glad to acknowledge the effectiveness of a catchcan (if any) at teardown time.
In the mean time I am glad to accept the risk.
Hope it works for you and others who have decided to place their undying faith and trust in catchcan engineers and profiteers, That's your choice!

At least if you have a flat it will smell good while you change it!

Glad we don’t have to do any of that crap. Here in NC, we have safety only inspections and no emissions testing.

How much you asking for the catch can!

It is not clear how that would affect emissions, but then its not clear how California got to be what it is!
Are you allowed to put pine scent in your tire inflation?

I believe Colorado has or will soon adopt CARB regulations, making use of a catch can unlawful, properly maintained a catch can shouldn't impact emissions - but therein lies the problem, the can requires maintenance and adds additional failure points to the emission system, so CA and at least CO ban them, I have one installed but in retrospect don't think it's necessary and I have confidence in Ford engineers PCV design, doubt that bean counters were ever involved in a decision whether to use or not use a catch can.

I have looked into the pro's and con's and have decided not to install one. I will however use CRC GDI intake valve and turbo cleaner right before every oil change (5K Miles). this should prevent any coke buildup on the backs of the valves without possibly messing with the emissions, warranty, or violating any CARB regulations (but no snog test for the first 5 years on new vehicles).

How can installing for example the jlt 3.0 harm a engine?
