Oil Catch Can. Yes or No?

[Jacob]

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.

I ordered the mustang and two extra filters.

Hi guys...which part are you guys referring to? They don't offer anything for Ranger let alone 2019...

Doc, would you mind posting the direct page link for the part your ordered?

CFM Performance billet valve cover/ oil filler breather. 2015/2019 mustang Ecoboost.(same filler cap)

I don’t remember what link I ordered from, you can call cfm@1-800 -943-1203, they are also available on eBay.

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.

And engines this new have that much blowby?

New rings , some blow by , breather is just a helper..

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?

Those are exceptions. Very rare. Again, breathers are band aids for bad rings.

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.

Breathers are not band aids for bad rings. Every internal combustion engine with rings has blow by, nothing rare about that at all. Breathers are merely another way of dealing with positive crankcase pressures and in our case, to keep all that gunk out of the intake.

Venting the crankcase to the atmosphere, via a breather, means fumes in the engine bay. Sure, old school racer folks do it and it works, but there is no getting around the vapors, they are there.

The only question here is how much under the hood vapor is acceptable to the user.

The breathers with the filter caps are better than the dump tubes used in the 1950's and 1960's. Those just dumped the oil onto the highway... but the end result is the same..... and that's why PVC systems were invented.. to deal with those fumes.

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.
