I installed the valve cover breather and have not seen any misting or fuel smell.

Correct, you should not have a raw fuel smell coming from the crank case. I would have Blackstone test your oil..
Regards
Just sent it off today! Im thinking I definitely have something going on for sure I will report back as soon as I get my report back. which should be possibly Friday/Saturday or Monday depending on Blackstone but I sent it priority mail 3 day.

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.

Also I know some talked about putting valves on the bottom of the can to ease the draining. I’d recommend taking off the whole can. I ended up hitting mine with brake cleaner as I had slimy chunks in it.

To those running the CFM breather, why did you order the Mustang EcoBoost (1-0103-3) version and not the one listed for the Focus RS (1-0103-9)? Are they the same? The part numbers are slightly different.

Not for me.

Catch cans are not about excessive blowby. It's about stopping oil and junk from going back into the intake system. Running open breathers are a band aid for engines with bad rings.
excessive blow by is recirculated and ends up in the same place . Breathers decrease crankcase pressure, reducing blow by.

Apparently, some more than others.....

Doc I just recently got one of these valve cover breathers and installed it on a Saturday and drove with it until Monday evening. When the engine would warm up and let's say i would stop somewhere run in and come back out and start my truck I would have a noticeable fuel smell coming into the cabin via the a/c system. And then when I went to inspect it Monday evening I noticed it had been "misting" a fine oil/fuel mixture all over my engine bay that reeked of raw fuel. Pulling it off the valve cover you could smell fuel all over the breather and it was slick with a fuel/oil mixture. Yours is not doing this correct?

Alright I ordered the Mishimoto setup to keep my valve clean but I also took a chance and ordered M-6766-A23S from Summit. This is the RH side that keeps the turbo happy and it's made by Ford. It's for the 2.3L Mustang so it may not fit the Ranger - we'll see.

Once everything arrives I'll see how it goes.
Following up on my own post. The Mishimoto catch can is installed. Pretty elegant design, the removal of the OEM vacuum tube was a MF'er though. Unfortunately, the Ford Performance part that's made for the 2.3L in the Ecoboost Mustang isn't compatible, not just because a custom bracket would have to be made but because the lines are not flexible putting the container in a location it cannot be which makes the whole endeavor futile.

I really want a catch can for the turbo side because I've seen what oil vapor does to turbos and intercoolers.
