The oil in the intake system, the constant vacuum on the rear main seal causing that nasty screeching noise, and that mushy oil-soaked rubber hose just waiting to burst, have me wanting to fab a catch can setup to route the blowby gases to it instead of back into the intake. I would probably vent to the atmosphere after the catch can. (don't tell the EPA)
And plug up the opening at the rubber air horn.
Besides removing the oily vapors that can cause detonation, it'll stop the rear seal problem. I'm probably running lean because of a vacuum leak there. I can hear detonation when I accelerate even when the air temps are cool (60F).

Would removing the blow by from the intake cause running problems? My concern is whether the mixture ratio be altered since it'll be only fresh air passing through the intake.
