Installing my dual catch cans today and noticed the intake tube has a hose after the MAF that is connected to the crankcase.
My question is: Does that intake tube hose also perform the same function of as the intake manifold hose in the middle? I.e. does it also vacuum the excess crankcase fumes and recirculate it?
If so, why is there no catch can for it?
(Curious about the hose in red. Blue hose is regular catch can setup.)
Thanks.
