Ford Performance M-6766-B23 Install - Is TWO catch cans better than one??

That is a great video. It will be interesting to see what you think. Thanks for posting this!

So, I installed the M-6766-B23 catch can over the weekend. Install wasn't too bad, but we'll have to wait and see what the results are.

Has anyone else installed this catch can (or the 2.7L version)?? If so, I'm extremely curious if you "caught" anything so far in your catch can. From my point of view the Ford Performance catch cans seem utterly pointless, BUT... maybe I'm completely wrong.

Links to Ford Performance:

• 2.3L - M-6766-B23
• 2.7L - M-6766-B27

Unfortunately these don't seem to be available in the Ford Performance section of the BN Gear Store. BUT... they can be bought for a MUCH better price on other websites. (Personally got mine from Lethal Performance.)

Another solid post!

I installed this one on my 2.7- Checked it after 1000 miles. It was bone dry. Since removed it. $200 wasted.

Devil's advocate here. If oil catch cans were essential to an engine's health, why wouldn't the engineers have included these with every engine?

BuckYeah

Every engine design is different. I have one on my turbo car and it catches a lot of gunk with a whole lot of water vapor in cooler weather. I’m pretty sure it would freeze solid if I drove the car all year in MN.
Also have the Ford Performance one on my Boss Mustang. It catches a small amount of oil (passenger side).
I think putting one on the 2.3 makes a lot of sense due to the deficiencies of that engine design.
You have to remember that blow-by can create denotation which at best retards timing and hence power reduction.
As I said before I removed the one I bought for my 2.7 as it caught nothing.
You don’t need one for every car and you don’t have to eat heathy either.

I hear ya, and thank you! I especially like the part about not having to eat healthy. My idea of a balanced diet is having a donut in each hand.

I was on the fence for a long time about getting a catch can and did as much research as I could on it. Ended up deciding to skip it and spend the money elsewhere since the benefit did not seem to outweigh the cost. I think these modern engines are designed pretty well to avoid needing this. Correct me if I’m wrong here too, but don’t these engines have an oil/air separator built in that kind of does this job already?

I think it’s a great idea for the 2.3 , not the 2.7.
Totally different engine designs.

Curious, what is it about the 2.3 that makes a catch can more necessary?

The 2.3L does have an air/oil separator. It's not perfect though, my UPR catch can has filtered out gunk that the air/oil separator missed. But catch cans aren't perfect either.

I actually don't know about the 2.7L engine to be honest. Have very little personal experience with that engine. Up until the Bronco it was only sold in the F-150, and everyone I know who has an F-150 either have the 3.5L or the V8 Coyote.

2.3 doesn’t have the extra port injection system as the 2.7.
2.3 is more prone to accumulate carbon deposits on intake valves.

Yup

So they say for the 2.3L turbo, the oil catch can is recommended. Would you recommend the UPR/Mishimoto type versus the FP one? Looks like they are 2 different types.

Not to mention illegal in some states.

I don’t quite know what the FP one does yet or why it exists. It’s not obvious to me, so I just decided to buy it while it was on sale and see what it catches.

I have an oil change coming at some point this month (depending on weather) where I intend to crack open both the UPR and the FP catch cans to see what they’ve caught. I should have a video on that coming in the next few weeks. I’ll post it here once it’s live.

did you empty out your UPR can when you installed the FP can?

I did indeed.

How and/or why would this mod be illegal?

BuckYeah

Certain states require all aftermarket components that can modify the emissions system to be tested by that state's environment & air quality agency before they are installed on a vehicle.

Which... if I'm being honest... really just means California requires it to pass CARB testing and have a CARB EO number before it can be installed. If it doesn't have a CARB EO number than it is illegal to own/operate in California, and your emissions inspector can fail your vehicle.

In practice, as long as the oil catch can system is installed correctly and the computer's sensors are reporting that everything is within spec, then most inspectors will use some common sense and pass your vehicle. But by the book, that vehicle should be failed.

This is also why many manufacturers for oil catch cans don't ship to California:
