It's a scam because nobody has been able to prove that the vehicle NEEDS one, as in, a stock vehicle will not function as intended without an aftermarket catch can. I've been hearing this BS for over a decade.
People say "oh my...look at all that oil, that 's bad". I say "prove that it matters, prove that it's relevant".
Answer is that in the vast majority of cases they can't.
When they then show me photos of dirty valves/intake, they say "see...look at all that crud, that's a problem". My reply is "prove it". Is the engine running fine? Yes? ....Are there drivability issues?...No?. Then what are you obsessing over?.
The best is when someone changes out the inter-cooler and remarks about "all the oil" at the bottom of the inter-cooler. Oh the horror !!!
I can think of one engine in stock tune that benefits from a catch can because of the poorly deigned separator. That's the BMW N54. Funny thing about that engine is that enthusiasts who bought the updated N55 jumped all over the catch can wagon because of the history with the N54, but the reality is that the N55 doesn't need one because BMW fixed the problem. In fact there is such minimal buildup at 100k miles that a walnut blast isn't even really needed at that mileage. Of course vendors were all over the forums promoting an alleged "need" for a catch can.
Catch cans satisfy obsessive-compulsive behavior. EOS.
