i'm not saying that diesels can't evacuate properly, i just figured that if there weren't any such routing then the gasses would have a more direct path to vent. I'm thinking that if the gasses are routed to the intake that it would (in my mind, i may be wrong) vent at a slower rate.

i'm not sure but with gas engines there is a scavenging/sucking effect because of the higher manifold vacuum... correct?

anyway, my system isn't perfect coz i have a fair amount of blowby, or so it seems, when i disconnect the breather hose i see this steady stream of gas...
i just want it to vent faster that's all... i feel it's responsible for all the oil weeping.

and does my theory about blowby=extra fuel make sense?
