Catch can causing oil pan leak?

[gb7FRz26]

For those that have it installed, do you actually catch a reasonable amount of oil? Are you glad you installed it?

You made me go check, thank you. Yes I'm glad I installed it.
Here it is today with 4,565 miles since the last oil change in October with about 75 milliliters or 2.5 ounces or 1.3% of the total 6 quart capacity of the motor. Passenger side only, I didn't buy the drivers side. Probably should have, I think my reasoning was comments from others online saying drivers side doesn't get as bad (why?) and B) passenger side was dead simple and easy to install.

Update: values seem close to the post I made 2.25 years ago, so the amount doesn't seem to be getting better or worse. Now at 2026 engine hours.
Update: 3.5 EB, non-PowerBoost.

There is an element of truth in the dealers position. High Crankcase pressure causing the leak... Assuming that is true.. it is only going to leak again most likely. My first 2.7 sprung 4 oil pan leaks.. i think it was due to blow-by under severe boost conditions. And also a weak EGR.. i have not looked at the newest 2.7s but.. my current 2.7 is not a leaker.

i have not put my trailer on it, loaded up.. nor stomped on the pedal until it is warmed up good. well. i am actually not going to push it to the floor. because i think that is when the gasket will likely pop...

The pressure to cause that leak came from somewhere. A properly designed and installed catch can won't interfere with the crankcase gas flow into the intake system. Hence any crankcase over pressure has another cause. So was your leak caused by crankcase over pressure? Or was it an improperly installed gasket or seal? The engine's crankcase oil level should not be close enough to the gasket or seal to be leaking directly out of the crankcase.So something else is going on.

and per the magnuson moss warranty act isn’t the dealer responsible for demonstrating that the catch can caused improper pressure before Denying the warranty claim? All they did was say it has a catch can which can cause leaks so we’re not gonna cover it

I agree. This one should go to legal action, I suspect Ford won't like that. The issue is there is just no impediment to crankcase gasses flowing into the intake. The fact that Ford offers one for other vehicles speaks directly to this. The dealer "just doesn't wanna..." and is hoping you'll go away in ignorance.

Yes, "the Magnuson-Moss Warranty Act puts the burden on the automaker to prove that a modification directly contributed to the failure of a specific component"

Not all catch can designs are the same. And there are plenty of examples of poor installs and faulty components.

So I don't know if you can say with absolution what "a catch can" can't cause or do. Especially the dual catch can solutions for the Ecoboost.

Agreed. Hence my earlier words about properly designed and properly installed. Also it must be emptied periodically. I've observed thatin the summertime there is little collected. In the wintertime I need to empty it about every 500 miles.

World Ford of Pensacola,FL and they are the worst dealer I’ve ever worked with of any brand.

anyone have the email/website for the ford customer rep folks that can help me open a case?

I can agree with the World Ford PCola comment. Whenever I bring my truck in for a repair, the first thing they ask is, are there any modifications to the truck. We will not cover under warranty is there is. 30+ days out to make service appointments, drop off on day of appointment and they tell you they will need to keep your truck for another week or two to diagnose. WTF. Why make an appointment.

I am all stock so not an issue for warranty work, but that is how they are there. I am not a fan of their service department, but close to work to get an oil change and tire rotation.

My 2021 2.7 oil pan looks just like yours and the truck has zero modifications. Waiting to take it in until this oil is due for a change. Noticed it during the last oil change but don’t want to waste 6 qts of fresh oil!

Let me know how it goes!

Hmm... I'm a new 2023 Powerboost owner... and as any new owner, I just ordered a bunch of goodies including a J&L catch can. I've always believed they are good to install on any engine with a turbo. But from the comments, it looks like the effectiveness of it for this engine is all over the map? For those that have it installed, do you actually catch a reasonable amount of oil? Are you glad you installed it?

Yes. Over a years time I collected over a quart, mostly in the colder seasons.

Here's my 2 qt jar after a year...

IMHO increased crankcase pressure won't cause the oil pan gasket to leak. It "could" cause the main seals to wheep a bit tho.
That being said my catchcan directions say to clean the screen every 15k miles.

Have you tried tightening the bolts?
