Catch can

[LokiWolf]

Installed J&L catch can before running out the door on vacation. I routed the line into the PCV as they show. The intake I ran under the wiring harness for the cam phasers, etc instead of on top. Seemed less likely to rub and cause a problem long-term.

I have seen people do both. Mine is above if I remember correctly, and no issues in over 20K, but I definitely considered the same. I think either way you are good.

Thought you did a good job explaining things.. try not to be so passive aggressive in your threads.

Thanks, I try to put facts and data out there.

You need to read more of my posts…I am not passive at all.

Sorry to resurrect this thread. Wondering if anyone knows if the J&L catch can for the standard 3.5L EB fits without any issues on the 3.5L H.O. EB in the Limited SPP? J&L has a part for 2022 Expedition 3.5L on their site (linked below) but there is no mention of the HO engine. Thanks in advance!

Yes I put this exact one on my 2022 Stealth performance. Fit perfectly. I optioned for the 3oz extension for the can but that’s up to you.

Don't waste your money. The newer eco boost engines have port injection rather than direct injection. That means the valves are constantly sprayed with gasoline rather than just having air passing over them. The direct inject air usually is a mix with re-ingested pcv gunk that a catch can would collect. The port injection sprays gas over the valve along with the re-ingested air mix, and the gasoline cleans the valve keeping it carbon deposit free. Just make sure you use good gas with detergents like mobile, and throw some fuel cleaner in there every once in a while and you'll be good. I almost did the same thing in getting a catch can, and I'm glad I learned about this from another fellow.

Is this true for a 2016 also because someone was telling me I should get a catch can I don't know what to do

No the 2016 is direct injection only. I believe in 2017 or 2018 they changed over to dual injection with both port and direct injection used.

Catch cans are Good for ANY ford EcoBoost. Period EVEN if it has Port and Direct like the 2018+ 4th Gens do.

This was my response to Expoxone originally:

Nope, you would be incorrect.

Whoever told you that was 100% incorrect.

The Gen2 3.5(Gen 4 - 2018+ Expeditions) Twin Turbo Ecoboost motor has BOTH port and direct. Under MOST situations the direct injectors are used, because of the more accurate fuel metering that can be delivered. Port is used for Cold startups, and under low load. The DI picks ups once up to operating temp and high loads, and under real high load and demands for fuel, both injectors are used.

Edit: Clarity on above. So basically when you are a greatest risk for deposits(High Temp and under load) the motor is in DI mode, and you are getting ZERO washing of the valves from the fuel.

It does not remove the need for a catch can. Heck some of the most powerful Port injected motors on sale today come with them(Some Hellcats), and are highly recommended in many port injected applications also. The port injectors even being used sometimes does help to decrease the buildup of deposits, but does not remove the risk. A catch can prevents the majority of what causes the deposits from ever getting to where it can cause them. PERIOD. A catch can is NOT about the short term, but the long term.

Port injectors were added in 2018(4th Gen) to the Expedition. They help, but do not solve the issues. See my above response.
