Oil catch can for a ‘19 MAX Limited?

[302Xplorer]

I’ve searched through posts here but found conflicting information. Some say it’s not necessary due to it not having “direct injection” but I’ve seen technical Specifications that say it does. Where am I going wrong? Do the 2019 Expedition’s need an oil catch cans like the previous generations? If they do, what cans do the other 4th gen owners like?

Thanks,
Ted

I do not think the Expedition engines “need” a catch-can. Installation of one could potentially void your engine warranty from Ford.

Some people feel they know more than Ford’s engine engineers and add a catch-can.

Just don’t ask what is the best oil or oil filter to use......

I think there are literally 5 threads on the 4th gen forum about catch cans. I admire your optimism in thinking that one more thread is going to clear everything up. Haha

Thanks; literally.

Yep, cause Ford Engineers have never made mistakes... Cam Phasers, fluid buildup in IC, Voodoo motor oil consumption(GT350's)...I could keep going.

In defense of the Engineers, sometimes things aren't added because of bean counters, or the average Joe's ability to handle the upkeep.

Hellcat's come from the factory with one, and the user is given specific instructions on how to handle.

2nd Gen 3.5TT Ecoboosts, like the 18+ 4th Gen Expedition has, actually has BOTH. It has Port injectors and Direct Injectors.

I put a upr can on our ‘19.

Ford master tech at my dealer said he recommended everyone put one on, but few people actually do it. His quote was “a what’s Ford going to say? You kept the engine TOO clean?”

It may not need it but mine pulled some nasty junk out so I’m happy I installed one.

I put one on my 2018. If I’m worried about it I’ll take the JLT plug and play can off, replace the factory hose and take it in for warranty.

All you need to know about direct injection...

What model # is the UPR can on your ‘19? Was it “plug and play”?

Any engine with a PCV system is going to benefit from a catch can. Period. Mic drop.

Has anyone been able to document a drop in knock retard after installing a catch can? My ls1 car had knock retard with the Oem setup. I added a catch can system built with some parts store stuff and cut that right down to zero. Had two filters and a catch can.

Can would have quite a bit of oil every so often. Filters would get misted enough to mess flow up and I could tell they needed changed because the way the engine ran.

No, Catch can should have zero direct correlation to KR on an EB motor. Directly it is helping keep intake valves clean, which improves airflow, so could have an indirect affect on KR, but nothing that is obvious on logging.

I have 100’s of hours using HPTuners logging on my 16 Edge Sport before I traded it in a month ago. I installed my JLT on it, and never saw any difference. On EB, a few things make the most difference, Manifold Charge Temp(Cool Air, upgraded IC helps), Octane(93 sees less KR, but Octane Boosters help too like Boostane and some off the Counter), good Gas, and Ethanol. Really want to help your KR’s, run a little more Ethanol, or get an Ethanol tune. The additional Octance, and evaporative cooling go a LONG way in preventing Knock.

Where does the pcv pipe the air back into the trac? How would it not send any oil into the charge? If guys are catching oil, it has to go in somewhere.

Compressed air gets hot. Hot air, absorbs water. Ethanol absorbs water. Boosted engines dilute oil, with gas. Water vapor, fuel and oil is what gets sucked into PCV. A normal running engine should burn it off. Worn rings and valves, let blow by into crankcase. Excess crank pressure run through a catch can, will help. Racers use them, but are running high RPM and boost. The Expedition should not need one.

I used a JLT 3.0 on my 2018 and confidently feels that it makes sense. whether or not I needed to, I won't know. but I know this; when it comes time for an oil change which I usually do myself on all my vehicles I have to empty the Catch Can, that's oil that did not go back into my intake. I am happy that I install one.

One more time for you...A Catch Can will benefit ANY modern motor and keep crud out of the intake.

It is even more of an issue on DI motors. The 18+ 4th Gen’s have the 2Gen EB 3.5TT, which has both Direct and Port Injection. One reason the port injection was added back was to help with the cleaning of the valves to partially remove what is coming in from the PCV System. Images taken of 2Gen valves have shown it does help, but doesn’t eliminate buildup. Want to help prevent build up even more, use a Catch Can.

Pretty simple concept to grasp...
