Found this about catch cans (and he's right - if it looks like starbucks, the bulk of the liquid is water and no it will NOT separate out as I've shown before. It's more of an emulsion.)
The starbucks looking stuff he talks about is more water than oil so when you think it's "full of oil" and it looks like a drink and not like the oil in your crankcase, then only a little of it is actually oil.
Here's the guy's quote - and he's a vendor -
----------------------------------
For everyone to understand about catch cans and condensation. Certain companies promote catch cans with all the water or moisture they collect and that gives honest manufacturers a BAD RAP. I will share the fact that most of the condensation / moisture a catch can collects is from the catch can and not the engine. Engines heat up so fast they force the moisture to evaporate and thus do not contribute much to the condensation / moisture in the catch can that gives it that Starbucks look. The catch cans actually introduce more moisture and create a steam or cleaning effect on the engine internals.
Thin wall and welded catch cans will generate a lot more condensation / moisture as the thicker walled sturdier construction catch cans will not suffer from the same extreme temperature sweeps. Thicker catch cans will hold temperature better while driving as the thinner units will cool quickly allowing them to continually produce condensation / moisture while driving and this will fill the can quicker requiring additional maintenance for no reason and create a lot of wasted time.
The design is critical to how much oil will be separated before getting into the intake tract and combustion chamber. I have been watching many re-sellers make claims that create fear or post millions of DI pictures of engine failures and giant bottles of Starbucks looking fluids collected. The proper design of a catch can is to be able to keep the catch can hot enough to evaporate the condensation / moisture and still stop all the oil.
Most catch can manufacturers run the coolest location possible to hide the lack of efficiency and this is why so many catch can manufacturers show all these pictures of the Starbuck's looking Mixture.
The fuel that gets by the rings or gets collected in the catch can is harmless and can be burned in the combustion chamber without any negative effects.
The biggest thing we see with all the late model engines is how much stronger the PCV system function is and how much more oil they introduce and scavenge through the PCV to be ingested into the intake tract and combustion chamber.
Please keep in mind that a catch can is an oil separator. Larger catch cans collect 2x to 3x more condensation / moisture being mounted in cooler locations and that feeds the sales pitch and bad rap for catch cans that are mounted and function properly in hotter locations than others. I have worked hard watching many so called experts regurgitating things like send it to Blackstone and wait till you see how much they collect in the winter etc. LOL, these guys are selling something that has nothing to do with the normal PCV function. A PCV system mainly introduces oil and fuel into the intake tract and combustion chambers.
Either way, this is just to inform the readers about the reality of a Catch Can / Oil Separator's function and I'm not here to get into a he said she said and would just like to state the facts. 50yrs of racing experience and engine building with the very best in the industry has allowed us to test and see these things and it was the reason we have been able to continually discover many variables about the PCV that many still haven't figured out. We're not just some aftermarket street car guys that sell products and never talk down to anyone or want them to be uneducated about our products or a products true function. We sell our Catch Cans based on the true value and function and deliver the very best hoses, fitting and components across the board.
I'm not pushing any product here and just sharing the information about how critical the oil separation is and the rest of the things that get thrown in to try and sell and promote these products is nonsense.
Thank you for taking the time to read this and feel free to PM any questions as I'm always happy to help you make the ( best-educated decisions )
