Why doesn't everyone install oil catch cans?

From what I've read so far, they filter out a bunch of nasty shit and the only reason manufacturers dont include them is because people will forget to drain them, So why are they so uncommon? should I not get one?

They're uncommon because people will forget to drain them.

Get an AOS and never have to worry about emptying it is my advice.

What is ofc system?

Only time a catch can is needed is on a high FI motor which intentionally has higher ring to cylinder wall clearance

Pcv...Damn mobile autocorrect

Can any engine have a catch can installed or only turbos?
I want my K1G engine to be inmortal

Because you're piston rings are fucking junk if you have enough blow to actually need one of these. Modern diesel engines use crankcase filters which perform a similar task, but is entirely unecessary on a properly operating 4 stroke engine.

dont catch cans release a bit of oil mist into your engine bay?

fuck that shit.

if you think blow by is the only reason oil gets sucked into the intake on a modern car you're a fucking idiot. Fitting you drive a mustang.

Nah a proper catch can should exhaust back into the intake.
