could be gunked up head slowing oil from draining from the head and instead blowing out the cam cover vent hose.
or shagged rings pressurizing the crank case, with similar effect.

It's pretty normal for them to have a little bit of oil in the intake pipe but yours sounds really bad. Have you checked the PCV? There 6-8 cap screws holding the engine/cambelt cover on so it's pretty easy to get to once you get that off (amusing you have the 4cyl 3SGE).

Most oil leaks are caused by the crankcase presure being too high.
