Hey all

2015 Mustang Ecoboost...Reddit/Google results and customer service reps are giving conflicting answers on passenger vs driver side blow by. Which one needs an oil separator worse?

Passenger...right?

I reached out to a few vendors...here are my results:

LMR says " I spoke with my tech guy and confirmed that the driver side oil separator is more beneficial than the passenger side. "

American Muscle says " You're absolutely right about the necessity for having one on the passenger side since that's going to be the real place you'll find all that "blow-by"

JLT says " The driver side is the PCV (dirty side) and typically the only side needed. "


Thank you!

The passenger side IS where it goes, but use the dual valve system on the
Ecboost.

 

I ended up putting them on both sides.........

 

I temporarily put one on the driver side of mine, and it was always empty. Even where it goes to the
intake, I unplug it from time to time, and it;'s always dry.

 

Thank you. Which vehicle though, please?

Now I'm reading it depends if your car is F/I or N/A, which, from my understanding in my case = turbo or not.

 

I would if it was a track car. As a daily driver though, one side is going to always be empty I'm reading.

 

As I posted before, the video, you have the ECOBOOST, use the dual valve catch can as shown.

IF you do not, then just the passenger side.

The PICTURE shown is a V8 Supercharged engine, not the same, AT ALL.

 

Thank you!

And thanks all.
