2.7 catch can.... this might help you decide

If you on the fence over whether or not to install catch cans on your 2.7L...this might help you decide

For all of you with pre-2018 Bronco's with a 2.7, there you go.

Can't tell if this post is trolling or not.
In case it isn't....the generation of the 2.7L in the Bronco has both port injection and direct injection, therefore a catch can is unnecessary.

I have yet to see a catch can on a 2.7L collect any appreciable amount of oil to justify its expense..

I consider this to be snake oil. As pointed out, the direct and port injection make this a non-issue on the Bronco.

If you want to put that $500 or whatever to better use, buy fuel with the best soap in it and drive on the highway for 30-40 miles about twice a month to clean out the gunk.

A bottle of Techron to a full tank of maybe 91 or higher should also help.

However, if you do none of this, your 2.7 will likely be just fine and you’ll have a lot more money in your pocket using the 89 from QT as normal.

One would think but due to the fact the port injection is only live at low speed it doesn't quite get it done & it will just take longer to show issues.
While not the 2.7 it uses the same dual injector tech. DYOC

Gentlemen don't believe everything you read on the internet...

Interestingly enough my 2022 Mach 1 has both port and direct injection as well.

The 2015 model year marked the first major design changes for the Coyote since its introduction in 2011. And then again in 2018, the Coyote was thoroughly reworked, featuring dual-fuel, high pressure direct injection combined with low-pressure port fuel injection technology for increased power and efficiency.

Last time I checked catch cans are pretty popular with Mustang guys. I have a can on each side. I never gotten a drop out of the drivers side since I'm naturally aspirated, but added it if I do go forced. The passenger side will consistently push ALOT of oil. I can fill it up the catch can between changes... about 4-5 oz with the JL. Boosting the Coyote with will only make it worst and show up on both sides. I've seem to have forgotten, Is the 2.7 forced induction? Rhetorical btw, be smart and do a little research.

I have the corsa catch can on my 2.7 and it's only been on there about 1500 miles. I checked it last week and it def had some oil in it. I didn't measure it but it was enough to pour out. Idk if that is significant or not or if it is worth it but there you go.

I have the JL. My experience is the same, Not as much as the coyote but enough to take that octane number down.

How does oil affect octane? Octane's job is to delay ignition resulting in more compression before combustion.

One can assume that the octane goes down based on how much oil vapor actually enters the intake stream

I would think that oil vapor would not affect the octane level per say, but would result in even less detonation due to not being as volatile as fuel. Kind of the equivalent of raising octane without doing so .
Either way, I don't see injecting oil vapor in the combustion chamber as a good thing .

So should I stop putting DEF into the air intake and windshield wiper fluid receptacle?

DEF?, that's for blinker fluid .....Cretin

2 things I've come across when researching when I owned a 4cy turbo JL Wrangler:

Some catch cans for the wrangler I've seen included a mesh inside the can. Basically like a course stainless steel pot scrubber. It kinda made sense to have it in the can to provide more cold surface area for the hot vapor to condense, capturing more of the oil and reducing the amount that enters the engine intake manifold.

The good oils designed for turbo charged engines by design have a reduced amount of vapor than the run of the mill basic oils. Use the right spec oil of course as they are also designed to help with low speed detonation common with turbo charged engines as well. SP+ rated oils I believe. Jeep even had a TSB regarding some of the JL Wranglers that had the wrong oil in them when they left the factory. They had to replace the oil filler cap that had the wrong oil weight printed on it as well.
