A proper working pcv system and the breather side of the system helps create a vacuum in the crankcase which helps with ring seal. That's why we run vacuum pumps on race cars. Most modern engines should not be experiencing that much blowby to warrant a open breather cap. Technology has come a long way since the 50's and 60's.

Can we focus on the topic of this thread? We aren't talking about race cars with vacuum pumps that help the rings seal... what we are talking about is production vehicles. all of which have blow by, and people who retrofit a system by putting breathers on them.

Your statement of "Breathers are band aids for bad rings" is just flat out wrong in the application at hand.

I guess your missed the part where i said a properly functioning closed system helps with ring seal. And modern engines just simply don't have the amount of blowby engines did 60 years ago. And that doesn't mean I'm saying there is no blowby. hen start another thread for open breather caps since this is about oil catch cans I guess.

Hey y’all, went with the Mishimoto catch can after researching catch cans for awhile. Needless to say I’m sold on them. Here’s what I caught after only 1000 miles of the can on my Sport XLT ranger.

Giving another update after 1500 more miles with the catch can. Noticed more carbon on the bottom of the can, especially when I transferred it to the glass jug. Just more food for thought for those on the fence about buying one.

The next thing to do here would be a carbon deposit experiment, putting the residue from the catch can and (in a well ventilated area) heat it up to about 210ºF until the liquid evaporates and see what is left after that. That will give you an idea of what will be coating your intake valves....

Like a volatility test? Ford's Synthetic Blend isn't stellar....

not exactly, I was talking about a residue analysis of the substances collected in the catch can to get an idea of carbon build up; I realize not all will end up on the valves because it is intended to be burnt along with the fuel mixture

All this talk about a catch can, won’t a can of fuel system treatment added a few times a year prevent excessive carbon build up on the valves etc?

The injectors are in the combustion chamber.

I just got an update regarding the Ford Performance Air/Oil Separator for the Ranger that has been in development for quite a while. The design has been completed and they have a quote out to their supplier.
However, due to the COVID-19 issue causing delays, it might take a few months to produce.
This is supposed to be a dual system (PCV/CCV), like the system for the ecoboost Mustang.

Good video on the Ford Performance Mustang version catch can.

When they start putting a 5.0L in the Ranger I'll get one.

They come in 2.3 L EcoBoost I4 as well.

Yup and I bought it... but it doesn’t fit the ranger. ? For the 2.3L mustang, Ford makes 2 the Pcv and CCV side. I bought the CCV side (turbo side) but it doesn’t fit the ranger and can’t easily be made to do so, therefore I had to send it back.
