Catch can or AOS
Vented or recirculating
Drain back or catch.
Street car or track car.
Motorsport regulations required.
Size....from my old CAMS manual
15. if fitted with any crankcase breather discharging to the atmosphere, each breather be vented into a catch tank
of minimum capacity of two litres for engines up to 2000cc or three litres for over 2000cc. Regulations for
competitions on unsealed surfaces may waive this requirement;"

I've seen $500 brand name "AOS" that were pretty clean on the inside, but, the intercooler was full of oil.
Meh, I'm bored
