How to reduce the dreaded valve carbon?

[EngineeredDetails]

An oil breather cap on the stock 2.0 will only serve as a very redundant PCV system. This isn't an alternative to utilizing an oil catch can. This simply relieves excess crankcase pressure. It doesn't capture vapor and oil particles. On your built Focus, keyword being "built", the breather cap helps with the extra crankcase pressure from what I would presume is added boost (more than factory boost). You would see greater benefits from a breather cap if you had a naturally aspirated engine and boosted it via turbo/supercharger.

Sounds similar to back when catalytic converters came out and industrious people would bypass them with a test pipe to relieve excess pressure. I'm not a mechanic, so I'm sure someone will point out the error in this association.

You are correct but it also has merit, if you reduce the pressure going through the pcv that’s less velocity and pressure that pushes oil into the intake. It is not a replacement for the catch can now did I claim it to be. But catch cans also don’t stop it all the goal is to reduce it as much as possible. And I put my first one on my build focus. But I’ve been running two on stock or just tuned ecoboost with seemingly less coking.
It’s not a redundant to pcv the catch can is a close comparison to a pcv. The pcv catches the vapor and oils with baffles then is drained back down.
A catch can just catches it. But same concept as pcv.
This is to help reduce the pressure and velocity of air being pushed into you catch can and pcv. If someone like you would be able to find a measurable amount oil oil per miles driver. Say empty catch can every oil change and mark the level or measure it. Then add one of these and see if that is reduced.

Can you post some links to the parts you used, and maybe a brief writeup of how you did this? And pictures too!

Has anyone had valve issues yet?!?
Let's see some evidence of a problem before trying to solve it.

These are a bit new but, this has been an issue with all di engines.
To be fair, I have never had a huge issue with carbon. But it’s well documentation in the focus community. I don’t worry to much as I’ve not had an issue but I thought this was cheaper insurance and very easy. This is meant to add some info for some that don’t know and let users decide if it’s worth it. Like changing oil early.

Ok so so bare with me...

You first...

Lol, don’t threaten me with a good time.

Looks like a well made piece, but I'm skeptical of the claims. I'd like to know the operating spec of the ball valve. I'm sure it certainly wouldn't hurt anything, but I also see no advantage with a modern OEM tuned MP engine.

I think any relationship with this & cleaner valves is purely coincidental.

Ok so so bare with me as this can be long winded.
So as the internet makes everything huge. I thought I would address a way to help reduce carbon build up or coking as it referred to on the intake valves of DI engines.
So to start off where does this come from? Well as your piston takes its compression stroke certain gasses get past the rings and pressurize the crank. When the crank case is pressurized that has to be relieved. So to save the environment the industry came up with a pcv valve to avoid vent to atmosphere. What this does is a series of baffles in a plate on the front side of our engines. And continues up to the intake. The theory is you add the extra crank pressure back into the intake and hope the baffles in the plate catch most the vapor and oils before the intake. But as we know it can’t catch all.
So several ways have been addressed for this. Such as better breather plates for the pcv with more baffles, and catch cans.
Now hear me out. I believe I have a third cheaper option.
Upr breather oil cap. So what this does is have a weighted ball that keeps vacuum while idles but once you get enough pressure it lifts and elevates it. Now since the timing chain and other parts are connected to the crank. This should in turn relieve crank pressure thus eliminating a lot of strain on the pcv valves also. Which would not have the extra pressure or gasses pushing up to the intake. The less gas the less coking of valves.
So far it seems to be working. I’ve been testing this on two ecoboost engines and at 120k they seem to have almost zero carbon build up.
So it’s only two but both have no more carbon or less than a port injection engine.
I stumbled upon this with my built focus rs just to remove crank pressure and the lightbulb went on.
These parts are only $65 and much cheaper than anything else. Plus it’s as simple as putting your oil cap on.

I had no problems with port injection. Another reason to get the hybrid.

Oh ya cause those have been trouble free!

It absolutely will not make more power. The ball actually works I’ve wrapped a paper towel over top once to see it did collect vapors. So it does push the ball up.
I think the only benefit would be for the scenario I described.
Now add this with a catch can and you really have protection.

Well the mask you wear should save you. Come on man really. It has a filter on it that will catch some oil if need be. But what you are suggesting would be so much oil your engine would be covered.
So it’s either catch some in the filter it has or burn it either way your sky will be falling.
I also dont think this is for everyone. But people like me who are more concerned with every other nation ruining the environment than ours I think I can live with a slight chance this would change anything.

When I had surgery I insisted the surgeon and nurses not wear a mask, .....or gloves. Also since other people litter even though I don't I decided to start littering....

Alright, may be I wasn't as clear and concise as I should have been. The breather, on a stock 2.0, would be nothing more than a redundant PCV valve (the breather using a weighted ball and the PCV valve using a compression spring). An oil catch can is not a comparison to to a PCV system. The PCV system utilizes an oil separator plate (with baffles) to slow down the air and allow the vapor to condense and then drop back down into the crankcase where the oil catch can will actually collect any particles that have a chance to condense. I believe the breather, in a case where you are not adding any more boost than what the PCV valve is already designed for, would serve no purpose. An oil catch can, if you are worried about carbon build up on the back of the intake valves would be the ideal part to purchase.

I’ve never had a battery last 400k miles in my vehicles. So let me know how that goes.

Well one set of masks is determined to work for specific things in surgery like spit and we know that the other doesn’t. Two things can be true at both times.
Not to mention I didn’t say I wasn’t green.
I think that we could make way more of an impact with any other minor changes to not worry about some vent to atmosphere with a filter in a 2.0 engine.
You were trying to come into a thread and take a dump on it. You do you man keep saving the earth while others will do our part and save our engines.
