Direct vs Port injection (Ecoboost/ Hybrid), catch can explained

[Mr Lee]

One more thought...Perhaps a fuel filter with a clear casing could be installed inline between the PCV valve and the manifold, which would also remove oil and particulates, while allowing the owner to monitor accumulations through the clear housing. If there's a lot of residue, then further steps such as a catch can can be installed, if not, then the factory baffle system is doing it's job as intended!

The Maverick 2.5 hybrid is not a direct injected engine. No need to worry about catch cans.

Yup. As far as I'm concerned the simplicity of port injection outweighs the small benefits of direct injection.

Because shops make good money on shell blasting.

How much did that catch can cost ya?

I don't think that you going to want to install a catch can if you live in a northern climate without cleaning it out very, very often. Almost everyone posting pictures shows that the contents are mostly water. There are videos circulating about people who have a lot of water freezing in their can, blocking the downside and pressurizing the crankcase at high enough pressures to blow out the gaskets. With a turbo you can easily get to crankcase pressures high enough to blow the valve cover right off.

Except that the factory system doesn't work 100%. I empty 1-2 tablespoons worth from the dirty side every 5k miles.

I dont believe they have them anymore. It was part of some testing i did for them.

The 2.0, 2.3 and 2.7 engines have a built-in oil separator, bolted onto the block where the PCV plumbing starts. That's why nobody is getting any oil in their aftermarket catch-cans.

In my 2015 Prius, because of how the PCV hoses were routed, the engine was prone to get gunk in the intake area. I installed an Oil catch can because of this. However, I have been told, just as RedRider has mention, that our engines are routed diffently and work very well they way they are. You can still install one, but, the rate of head gasket leaks in 2010-2014 Prius engines to Fords escape engines is different. With Ford in front. My 2015 Prius had different piston rings installed to help minimize the blow by issues as well. Toyota's, Honda's I have seen oil catch cans installed and they do work!!

They are standard equipment of Ford GDI engines. There is one on the side of the block of your 2.0, so there is no need for you to add a second one.

Folks, I would lean more to Redrider's advice. Not saying he knows it all, but the design of the Maverick Hybrid engine has mitigated this issue.
