Mishimoto R&D: 2019+ Ranger Catch Can Kit

[CoastieN70]

This video shows Direct Injection Fuel System. You will notice that the fuel is introduced without ever touching the back side of the valves.
In a older conventical fuel system the fuel was introduced on the back side of the valves and had a cooling effect and it sorta washed over the intake valve.
Oil is introduced in both systems via the PCV system.
In the older system the raw fuel helped wash and combust that oil.
In the GDI system this can not happen.
This then allows a large portion the PCV introduced oil to bake on the back side of the valves. NOT A GOOD THING, causes sticky valves and disrupts air flow making for a rough running engine.
A oil catch can will help stop this from happening...

That certainly is the theory and the marketing. But in the absence of real testing showing a benefit vs control, it's certainly not science regardless of how many papers are cited relating to the general concept.

My family owns and operates a Ford Dealership. I’ve filled out warranty claims myself, it’s a “real thing” dude. Telling yourself it is not an issue will not make it go away. It’s not a matter of if but when. I really like the EcoBoost engines and I bought this vehicle knowing that if I were going to keep it over 3 years or 60,000 miles that I would need to address this issue. And although I wish it were addressed before it left production, it is a small and fairly easy fix that can be maintained in the same intervals as my regular oil changes. The truck is perfect for what I use it for, it’s a small price to pay.

Great, so you actually possess long term test data showing that this particular product shows a benefit vs control? I'm sure we'd all like to see that data!

Don't buy one. Simple. We believe in the benefits. We will run them. Having the throttle body off after running one shows me the intake is dry now. There was plenty of oil caught in the catch can. Proof enough for me that I don't have oil going back into the system. Don't want oil in the system where it really shouldn't be. Oil not getting in the intake, valves, combustion chamber, etc is what I want. Cleaner air/fuel mixture. I don't need 300,00 miles of someone's testing. I've run catch cans for 20 years on all of my vehicles. Clean engine is a happy engine.

Hey, if it makes someone happy, I have no problem with them getting it. (Why would I?) What sticks in my craw is someone quoting generic papers to imply that this particular product has a statistically significant positive effect on this particular engine.

Let me put it a different way. Do some GDI engines have issues with buildup on valves? Yes, and nobody has argued about that. Does every GDI engine have issues with buldup on valves? No! Why are some different than others? Engine design across generations probably plays a role, duty cycle probably plays a role, chance probably plays a role, who knows what else. Is it possible to predict which specific engine will have issues? Not as far as I know (if someone has a credible citation, I'd like to see it). Is it possible for for an engine with a catch can to have no issues? Yes! Would that engine have had issues without the catch can? Nobody knows! Without extensive testing (which Ford has done and aftermarket vendors have not done) there simply isn't any data about the prevalence of these issues nor is there data about how much a catch can may help (or even make things worse). If the marketing is "this product can make your intake drier and that will make you feel good", cool. If the marketing is "look at these (old, relating to different engines) scientific papers about this problem that affects your engine, and make sure you buy this product which will fix that problem", that's verging into snake oil territory in the absence of any kind of evidence. (It's worth noting that the catch can manufacturers themselves generally avoid making such explicit claims because they don't want to get in trouble with the FTC. They will generally describe the mechanism, but not assert that it will have any specific impact on engine life, etc.)

Could you share the documentation from Ford in which they've researched and concluded that the 2.3L EcoBoost does not accumulate carbon on the valves?

Thanks!

You seem to be asking me to defend a position I didn't take. Excellent dodge of the actual point, though.

I can’t wait to install mine.

i get what your saying, but there really are not many (if any) rangers with 300k on them. the point of the matter is that DI engines are what they are & if ford is only going to warranty to 60k there in the clear, so why would they say or do anything about an issue they seem "not our problem".

the engine will run great for that 60k & you may get your 300k without any issues, but those of us that believe that a CC is worth the cost for a piece of mind weather its snake oil or not.

I have dumped a lot of nasty liquid from the last CC i had on a 2015 eco mustang (just FYI)

Again, I never claimed that people didn't dump stuff out of their catch can, I just pointed out that's the kind of dramatic demonstration that looks impressive but doesn't mean much. Does the can block 100% of stuff, or does it let some through? If it lets some through, is it blocking only stuff that doesn't really matter and letting through stuff that does? But hey, if a catch can manufacturer were to offer a warranty that a GDI engine with their catch can will never require any valve-buildup-related maintenance, I'd buy one today.

Hey everybody,

It sounds like all of the points that I would make have already been made, so thanks!

Like others have said, the biggest issue is not the burning of blow-by, but what it does to the valves and everything before the cylinder. Without dual-injection like the new-gen 3.5L any oil vapor and carbon is going to build up on the back of the valves. Below is what we captured from the first-gen 3.5L EcoBoost and what bad carbon buildup can look like (this image is from a VW but demonstrates the concept well).

Unless you're building a bio-diesel system, gasoline engines aren't designed to run on oil—sure, the engineers account for blow-by in the cylinder, but that comes at the compromise of lower cylinder pressure and timing adjustments to reduce knock potential. The engine will always perform its best when it gets clean air and clean fuel. It's not going to be noticeable on the butt-dyno, but over time it adds up.

Haha, I have no idea what you're talking about

Thanks!

Best way to sell something is to promote fear. If you need it to sleep at night buy it, other wise relax and enjoy the Ranger. I am pleased that I do trust the engineers to make a reliable product, and the fact they all manufacturers put a load of road miles on the vehicle before sending out for production.

Will it cause any issues if you DO install a catch can ??? No.....but your wallet will be a little lighter
Will it cause any issues if you DO NOT install a catch can ??? Maybe.
It won't increase your MPG's or HP or TQ, but it might help to keep those numbers in the long run. For me, it's like insurance for my engine. I emptied the catch can on my 04 Lightning on a regular basis. Did it keep every drop out ? No, but I was glad it did catch what it did.

I see it the same way. If it’s reasonably priced I’d go for it just for the piece of mind. I’d rather spend a few bucks on it now than regret it later. Plus I like bolting things on my truck. Lol

I’m not feeding the troll anymore. If you need scientific evidence to prove that eating 4 meals a day from McDonalds is making you fat, I’m not your guy. Everyone is showing you the weight scale and you’re screaming you need more proof. We were just trying to be helpful, nobody actually cares about your weight. Bye bye.
