    Ummmm. I'm pretty sure we weren't referring to you. But thanks for being a good sport about it.

    With the new port/direct injection, is a catch can really necessary? With straight direct injection I can see it but why on an engine that has the ability to keep the intake valves clean? Personal preference/experience? Curious.

    Although a catch can DOES help the valves stay cleaner, it's main point it to capture blow by. Boosted engines will always have more blow by, so yes it is. Oil vapor also hurts combustion, so as much of that as you can keep our going back into cylinder, the better.

    Cause I always fill my oil containers to the top and there is no room for catch can contents. The contents will go with the oil to get recycled, but I barely drive these days(wife and I both work from home.) We drive MAYBE 10 miles per day, so I produce very little waste oil.

    I would think in 2019, 50 years since the recirculating of crankcase oil and 40 years of EGR science, and now, back to port injection, the burning of oil and carbon in the combustion chamber, engineers have this issue contained. Iím all for choice lol. Iíd just be emptying it every time I stopped. If it was a serious problem engineering and R&D would solve it. Ford, Gm etc donít need us coming back for large dollar fixes like the VW gdi system.

    Why did you ask the question and then argue against the answer?

    ecoboost does not have an egr, it using the VCT.

    PCV recirculating is for emissions only. It is not ideal for combustion. Again, boosted engines have a lot more blow by. A manufacturer will never have a catch can for many reasons. I think BMW has some type of catch can on their v8 twin turbo, that is all i know of. Also BMW owners mostly lease, have work done at BMW and BMW is pretty stringent on service.

    Hahaha. devils advocate man. I wasnít arguing. I would call it discussing. Wonít know if I donít ask. If EGR is accomplished through VCT is it not a different answer to the same problem? Like I said, ford installing an injector in the intake port, solves a large amount of the issue with build up on the back of the valves. This is my first Ford man! I gotta ask.

    Itís a matter of...I put this on my truck and look how much stuff it collects. I feel so much better my engine didnít have to burn this. Well thatís what it would be for me if I had one anyways.
