Slightly less going away from the PCV inlet.Do you know if the other valves look the same?

Okay time for a catch can. You just sold me on it. Just want to see the results of @turbotigger604 to verify it helps50k stock 2016-buddy's valves on his EcoBoost Mustang.
Next week ill be pulling the intake manifold!Okay time for a catch can. You just sold me on it. Just want to see the results of @turbotigger604 to verify it helps

It's all been put on hold right now, with all this corna bs. Been working from home, car hasn't been a focus right now.Any more pics you can share?
GotchaIt's all been put on hold right now, with all this corna bs. Been working from home, car hasn't been a focus right now.
A catch can does nothing to reduce crankcase pressure. It It only catches some of the oil vapor present in blowby gases.I installed an UPR CC on my car at 5k miles. The car now has 19k miles, and I recently emptied the CC when installing a bigger turbo. I would say there were 3-4 oz. of oil. However, now that the car is tuned for this turbo and has full motor bolt-ons, it gives me more confidence because I'm peaking at WOT at 25 or more lbs. boost. Also, a CC helps reduce crank case pressure and this can't hurt. However, I do agree with those that it probably isn't needed on a mildly modded or tuned car.
Ford designed, built, and installed the PCV system, on our cars, on purpose.Did an oil change this weekend, I don't know about the rest of you guys but I don't want this shit running through my intake...
1. The carbon that accumulates on valves and piston tops can't be wiped off with a rag. It gets baked on. You need to use a solvent or abrasive media, to remove it. The photos, in this thread, of carbon on valves are no where near enough carbon to produce any noticable symptoms of a poorly running engine. Look at some photos of early 3.5 Ecoboost engines, before Ford solved the problem. They accumulated way more carbon.I'd like to ask a few questions if I may.
1) every 10 k when you pull the intake are you taking a rag to the intake valves or just eyeballing them?
2) what does the top of the pistons look like?
Carbon build up there = hot spots and pre-ign and a bunch of other issues.
It is great to hear your service reports, Thanks for that.
But the guy that thinks a few runs up to 4500 rpm a month, and a guy that runs it upto red line most shifts will have different outcomes.
Higher rpm puts more oil in the crankcase vapors as the crank whips the oil.
For #3 in freeway mode yes. In autocross on sticky tires there is a high probability of oil getting whipped around by the crankshaft. I see 1.2 lateral/braking Gs with Falkens. See Walt's post on the NĂĽrburgring Mustang. So for high performance (autocross/track) drivers a catch can is probably useful. Especially since burning oil lowers the octane rating, which will reduce your power.1. The carbon that accumulates on valves and piston tops can't be wiped off with a rag. It gets baked on.

2. Top Tier Gas and API SN+ and SP oils were specifically formulated to help mitigate carbon buildup and LSPI.
3. On modern engines, the crankshaft doesn't dip down into the oil as it rotates. Our engine is pressure lubed, so there is no need for that.
