Which is the best catch can

[Bomlodr]

Ask yourself this why does a Ford accessory Branch offer this for sale but it's not included from the factory? Because it's only design is to part your wallet with your money

Much like over landing equipment. It's only design is to make you part with your money.

Changed my oil today after 2500 miles and 10 months , so it was time to check the Ford catch can. I had a little water and some brown gunk at the bottom of the can. I disconnected the hoses but still removed the allen screws to get a good look. To be honest, next time I will just remove the allen screws as its the easiest way to remove the can without the chance of breaking the clips. I like being able to see whats in the can, so why not remove the cover.

Dang people are sucking down the haterade today.
So I’ve had mine since roughly month two with my truck. 98k miles and I dump my can every 2-3k miles depending on time of year. Winter it catches a ton of water.
everyone can have their opinions regarding them. At the end of the day, those that have them see what they catch and know “yay it’s in my can and not on my valves”

now I went with aftermarket. I’ve been happy with my mishimoto can. Install was a pain but it’s well made and easy to clean. Options weren’t as prevalent as they are now. Knowing ford makes one, I’d probably go with ford if I could do it again. ??

I agree with you. I too have the Mishimoto catch can and was a pain in the ass to install the hoses. My wife thought I had a fight with our cat because my hand and forearm was all scratched up lol!

I empty mine out everytime I do an oilchange and I do get a pretty good amount in there so I know it works.

None of them they are a snake oil product.

I'm still trying to figure out after all these years how people randomly decide they need this product for their vehicle.

I would read about DI motors then Edit your post.

Disagree with the snake oil aspect of Catch cans on Turbo DI engines. My 60K mile Edge Sport (2.7LTT) had one since 800 miles, tuned with a strong LMS 93 Octane tune dropping some big power from about 8000mi. Every Oil change I would dump about 3+ oz of fuel diluted oil out of the can. When scoped at 50K to check out the intakes for carbon build up, they looked really damn good for the mileage and for the amount of boost the engine has been running.

So... yeah I took the J&L catch can off when I traded the sport in, and just sent it back to J&L to get converted into the right setup for the ranger.

DI engines, especially tuned ones, will mess up intake valves in a hurry.

Then why is the catch can not standard equipment. I'll wait...

No need to wait, here is the answer: Because the general consumer is terrible at maintenance... and checking a can that can fill up with oil and fluid and if it does fill up, cause a CEL or some real smoky fun... is not something the MFGs can handle.

MUCH easier to just charge a customer $2500 every few years to walnut blast the intakes.

Thats the real reason, liability is passed off the mfg to the consumer. There are SO many things in modern cars that are there just to get the vehicle over the finish line and out of warranty that could be done better, but would either increase liability on the MFG, or labor on the consumer.

Everyone wants an iphone car... heck look at Tesla bros being completely mystified when a tire goes flat on their cars assuming Tesla will just fix it all.

It becomes part of the emission system, which is under gov regs, it would need to be monitored and able to set a dtc, this alo ng with trying to figure out when to empty makes it impractical for mass adoption.

There's one on the drivers side of the engine, it's empties into the oil pan when it fills up. How great a job it does is the only thing up for debate.

That may be an oil separator, but I can tell you now that my UPR catch can catches a whole lot of stuff that comes directly from that port. If I am not mistaken that port is the built in PVC system as well. I actually own that part in my stash. And after looking at the service manual, it will be a bear to replace tucked up under the intake manifold.

It was hard enough just swapping hoses for the catch can. Very tight area to work in.

I'm on your side, I have a J&L downstream of the built in separator before it goes back into the manifold and it grabs a little of everything.

Some fuel, some condensation, some oily gunk... none of which do I want sitting on the top of my valves.

If it's a snake oil product why is there one built into the side of our D.I. motor? I'll wait.

Anecdotal story, wife's vehicle is D.I. also, smaller engine, different brand. Valves were so corroded it needed blasting at about 40k and all new coil packs and plugs. Manifested with misfires at ~40k mi

Where’s the proof? I’ve never seen a documented problem on a Ranger.

Umm... all DI engines have the issue... by design (unless they are the newer dual injection style where there is a set of port injectors that work now and then like the updated 2.7L Ecoboost). Lack of port injectors on most DI engines leads to the oil vapor coming out of the crank case to burn onto the intake valves. This is what catch cans capture to remove that oil before it hits the hot valves.

And since it seems doing something like google is beyond for some, I did it for you: https://tuningpro.co/ford-ecoboost-carbon-buildup/ That one specifically talks about Ecoboost engines, but it covers almost every DI engine made. Some are more prone than others just based on the crank case breather method. But all DI engines have the issue. If a catch can is catching anything, then its helping.

 

[Joejk3d]

Or... don't use one... no one cares. Everyone can maintain their ride how they want, and walnut blasting when you start experiencing CELs or just bad idle, and performance for no real reason... is definitely an option.

Not my first day. 42 years in the automotive industry. I would not trust a “technical writer” for my information. I am still waiting for proof this is a problem on the Ranger. Your blanket statement that all DI engines have the issue simply isn’t true.
