I have thoughts. I installed a catch can on my Focus ST and was glad I did when I saw the gunk and crud I was not putting back into the 2.0ās cylinders via the PCV. Even though the 2.7 in my F150 is DPI I installed a UPR catch can in it. Same story, lots of gunk intercepted and not reburned or deposited in the intake manifold.Anyone put any thought into oil catch cans on the 2.3L since it is direct injection?
This will be the first engine that I've owned that doesn't spray fuel into the intake manifold. Worried about the PCV value shooting junk into my intake manifold/values that won't get naturally cleaned out by fuel.

On combustion engines, some air pressure from the cylinder can get through the piston rings into the crankcase. This is known as blow-by, and some amount of blow-by is natural for an engine, especially a turbocharged engine.what does a catch can do for the engine?
Ya know.... I don't actually know where the PCV valve sends the excess air to. I assume it's post-turbo, but at the same time I would expect the crankcase pressure to be much lower than the pressure out of the turbo... so maybe it is pre-turbo? Or maybe they have some manifold vacuum thing that allows them to send it back into the intake manifold? Not sure.Great explanation, thanks. I am a mechanic but I work on big industrial engines running on natural gas. So the blow by goes to the intake of the turbo?
That is the one question I have, and I don't think we have an answer yet.Any warrantee concerns with installing one?
Excellent info and well-explained.
If there is an engine issue and that could possibly be traced to that part they could void warranty work.Any warrantee concerns with installing one?
Itās a non-standard non-factory approved part so there is significant potential to void the warranty. My gt350 has a factory supplied one approved by ford. Typically under normal driving I only find blow by in the passenger side one. Drivers is always clean. Now after a track day I find it in both. Iāve got the 2.7 Iām my f-150 and have had 0 issues. If this truly were an issue ford with offer this part, just saying. And as an fyi Iām a mechanical engineer who has torn down and rebuilt every type of motor.Ya know....

Usually air travels to the engine along the following path...
Air intake -> Air box -> Air filter -> Turbo -> Intercooler -> Throttle body -> Intake manifold -> cylinders
But I don't know exactly where the PCV is connected in that chain.

I know @Bronco wild outdoors mentioned during his live stream tonight that he was going to look into it.
