Catch Can and CC Ventilation

[Yukiwari]

I installed catch can for Elantra MD 2.0 MPI not inline with pcv valve but elsewhere left side, after 3 days and 500km i saw little oil in can, is this mean well working catch can and well ventilated CrankCase , Climate Conditions is 118f-125f during day, oil is Motul Eco-Nergy 5w30

i want to make sure CC is well ventilated to avoid seal leak

I think you put this Catch Can on the Breather Side, it really should be on the side with the PCV

Correct, the pcv side is under vacuum to the intake manifold where as the other side is primarily to allow fresh "makeup air" into the crankcase... you'll have to switch the side the PCV is routed in for it to be effective.

i marked where installed the catch can

catch cans go on the vaccuum/pvc side to catch oil etc being sucked out of the crankcase.

Do you understand how a catch can works?
