He didn't say condensation, he said vapor.

Vapor condensates into liquid.

You do realize the purpose of the catch can is to catch the vapors and collect it as condensated liquid.
No, actually I thought the purpose was to catch the oil and particulates carried by the PVC vapors. Your own photo seems consistent with that. If you want to condense all the water vapor too, I think you'll need a lot bigger container and keep it significantly cooler than the engine. Near as I can tell, water vapor is no problem for the engine to recycle. Heck, ambient air is loaded with the stuff. Oil you can make an argument for, and particulates definitely good to catch. That's my take on it.

In winter, you will see a lot more water condensation. Sometimes it will drain out looking like a milkshake. Catch can placement has some to do with it as well. If your engine is operating at the correct operating temperature, there shouldn't be much water vapor in the crankcase to condensate.

In the winter months. You’re going to get a lot more moisture / water vs oil in your can and have to empty it more often. This is nothing new. It’s well documented.

Well still no ending to this. The dealer is still trying to figure out this issue on his old truck. He visited today.
He is a guy who went off the olm vs doing 5/6k oil changes. So maybe a oil passage is partially blocked somewhere.

Has anyone tried the Corsa Catch Can?

Could you imagine 10 of those portions which would be 80,000 km going into the engine to be burnt off? Spark plugs, valves and catalytic converters would eventually get carbon buildup.

Picture an eye dropper with 100 drops of that diluted into a 5 gallon jerry can. It's not a real problem for port injected engines like the hemi. The fuel literally washes it off the valves and converter is much farther downstream and not effected.
Now the hurricane, yes, absolutely want to run a CC as its direct injected and there is no fuel to dissolve that junk.
If you really want to keep your engine clean, I'd start with running a premium oil that does just that (HPL, Redline, Amsoil too probably) and change it <= 7000 miles. A lot of the cheap oils don't have enough detergents causing carbon and sludge to build up, this is 1000 times worse than not using a CC IMHO.

Ok, well think of it as contaminating your octane level, throwing in some oil and water vapors as opposed to not, I’ll just enjoy emptying the cc every oil change knowing it’s not being burnt off.

I run 91 octane all the time, and there is far more moisture in the air on a rainy/humid day then the engine is getting from the PCV system.
I'm not saying "don't run a CC", I'm just saying its not as much of an issue for a port injected engine as it may seem when looking at those beautiful fluid samples being shown off.

It will help still help keep things clean but not as much as a need as other engines for sure.
Also remember a quality catch can does not use wear and tear. Once you buy one you can use it for all your future purchases just change the tubing and maybe a check value or 2 depending on what you drive.
That's the only reason why I run one on my Hemi was I already owned an 2 can setup from a previous vehicle.

Or, hear me out, it's doing more good than your opinion thinks it does. Even on a port injected engines. It keeps more than just the combustion chsmber clean. Ever remove the throttle.body on a 100k mile engine and see how dirty the intake manifold side of it is? This build up can cause idle issues. Oil coating on inside of intake manifold also covering the IAT sensor effecting its readings.
Will the average driver notice any difference? Probably not because they'd never install one in the first place, let alone do proper maintenance to keep it empty. And a full catch can, that was never emptied, will cause more problems than not running one.
Much like the guys who are meticulous about hand washing their trucks and ceramic coatings and detailing. Or those who do UOA tests, run quality full synthetic oils, only high quality filters, change oil at shorter intervals. The guys changing diff and trans fluid with less than 60k miles. The ones who will only run a specific brand of tires. Running a catch can is just that extra step to take care of our trucks above and beyond factory recommendations.
