Oil Catch Can. Yes or No?

[bulldogger]

Installed the Mishimoto catch can Saturday 4/10. Two hours to install totally sucks if you have large hands which I do. Be prepared to loose some skin squeezing your hand between frame and body to release the clip on block mount, the worse part is pressing the new clip down
on the Mishimoto house mount. Intake manifold side is easier

IIRC the Mishimoto install video indicates a 2.5 hr install - so congrats on your time. Besides the satisfaction of a job well done you are hereby entitled to post pics of what your can has collected, make sure you use a clear glass jar with measuring notches , proper lighting and an accounting of miles driven.

Is there a posting of a oil analyzes before and after installing a catch can. I have read thru most of this thread and probably missed it. I didn't get my 1500mile breakin oil checked, next oil change I will. I may not even need one.?

That's the kind of testing you'd expect the catch can manufacturers would do, right? And then publish that data to prove the can is actually beneficial.

They don't. And I find that telling. Anything to show that a catch can is cost justified on our specific Ranger motors, you know, the motors that already come from the factory with a separator.

Not sure what testing the crankcase oil before or after would reveal or accomplish much of anything, with or without the can the same vapors are being pulled from the crankcase but the theory is that the stuff collected in the can helps prevent deposit build up on the valves.
I did see one study that ties GDI intake valve deposits more to the exhaust vapors from the action of the CVVT - Ford is using an EGR system so I'm don't know whether to what extent that is relevant of the 2.3.
Anyways I can now say I "modded" my powertrain and maybe even post some glorious pics of catch can harvesting.
If you desire to see some questionable intake valve claims I think a very good source is from the chem makers like CRC who post before and after pics and some percent of deposits removed from the intake valves - you know like 89.999999% deposits removed.

I'm well read on the subject, and have seen (most) all of the videos and talked to mechanics that are knowledgeable on the topic also.

None of which are showing, or know, or can provide data that definitively shows positive, or negative, results of a catch can on our Ranger motors, the motors that already have a separator from the factory.

Well around 50 to 60K when most warranties are up and over and the buildup on intake valves is causing issues that would require a walnut shell blast to fix at a hefty expense, you can tell us it wasn’t worth the forward thinking on our parts? Bet most if not all that are using them won’t be half as bad as the ones that did nothing. It’s a known issue with TDI engines. So the question now becomes, do you feel lucky today? ?

Cans are beneficial yes they have a separator on both Ford ecoboost 2.0 and 2.3 engines from the factory, and I have seen coked up intakes valves that require cleaning. The fact that you are catching oil in the can kind of reinforces the fact that fords factory separator isn't doing all that well. Catch cans reduce the amount of oil blow by that coats the intake valves. If you don't think they work that is fine then don't use one, some people also believe the word is flat to each there own

Can I sell you a can of carburetor cleaner for your Ranger? That worked great for years and years and years.

You act as if there are no 50 to 60K Rangers on the road? And you're "assumption" is Ford hasn't addressed the issue, even though our motors come from the factory with a separator mounted on the engine..

Show me a GDI motored 2019 or newer Ranger with 50 to 60k that has the issue, and one that has a catch can that doesn't have the issue, and I'll start believing. Until then, you're using flawed data.

I'm speculating all the captured fluids in aftermarket catch cans has more to do with the long uninsulated lines that run up to the catch can, those lines cool the hot vapors, producing liquids, that the can then catches. Fuel vapors that would have washed over the valves, helped to clean them and resulted in less build up. And that's why Ford places the separator right on the motor so the vapors don't cool off and condense.

It's really not to much to expect a company to do R&D to prove their product on new applications. Well that's how it used to work.

Someone is a little emotional about catch cans. I’m puzzled though, if you dislike them so much, why do you stay on this thread? Are you that bored in your day to day?

I for one have pulled out more then enough mixture of fluids to justify my purchase and I will continue to post updates as time goes along. With my fancy glass bottles and all ???

In my opinion, no. I’m pretty sure Ford does super thorough testing for 150,000 miles and absolutely tortured this powertrain in the testing phase. If there were issues I think they would have found them and resolved them. If Ford can’t be trusted to do testing on their powertrains, maybe we should’ve all bought Tacomas ??‍

P.S. I am not worried about the longevity of this drivetrain whatsoever or I wouldn’t be here. I love my truck

The wizard says pay no attention to what is going on behind the curtain. Take 2 cans of carburetor cleaner, and call Mishimoto in the morning.

The effectiveness of a can shouldn't really be based on what it catches, but rather what it misses and allows to re-enter the intake. Unfortunately, there really isn't a way to quantify what's missed, but if the outlet hose going back to the manifold is dry, that would be an encouraging sign.

The reason that the amount caught isn't an accurate measure is because the contents of the can primarily consists of (1) actual blow-by product that is successfully condensed and contained by the internals of the can, plus (2) condensation that forms from simple temperature differences.

The amount of actual blow-by that passes into the can is affected by vehicle condition, driving habits, oil volatility, environmental conditions. The amount of condensation is also affected by mounting location, can design, can volume, can fill level, filter contamination level, and possibly even hose, union, and connector construction, diameter, length, and routing.

Ultimately, a can that "catches" a lot could just be condensing lots of moisture from the environment. Regardless, if it is letting oil pass through back into the manifold, it doesn't matter how much you find in the can.

Then in lieu of a catch can miss measuring meter the obvious solution would be to install a secondary catch can to catch what the primary can misses. But it might get expensive, some of those catch cans are pricey.

Please...no disrespect intended but Im not sure why owners think its a good idea to redesign vehicles and other recomendations engineers make. There are years of design and testing that goes into these things.

Catch can: if it needed it, Ford would have designed it in. I would venture to guess that a very large number of Ecoboost engines run fine and for a long time without it. There are a tiny few (%) that feel it needs it.
Oil: Ford knows what kind of oil it's engines need. Not sure why some owners feel they know more then the folks that engineered it.

Just because Fords engineers didn't add a catch can, or anything else for that matter, doesn't mean that the truck would not benefit from it. Engineers need to work within a budget when developing any new vehicle. Im certain that the company bean counters have as much a say about what's included and what's left out as the engineering team. In this post we talk about catch cans that are missing. In other posted we hear about the peeves of buyers who think Ford should have included A,B,or C widget. If Ford were to include every single thing that us consumers think that they should, we would be paying twice the price for our trucks.
