running a draft tube instead of a closed crankcase

89 tracker 1.6L 8 valve fuel injected in my zuk.
thinking of plugging the hole in the plenum before th ethrottle body where the crankcase breather goes into it.
any problems with then just runnign a draft tube from the crankcase breather down the firewall?
i know its no emiisions legal, but the zuk is being used hard in ravine sand landing/driving on its side ALOT. whenever i am hard on the passanger side, the oil wants to come out the vent and go into the intake causing lots of smoke or hydrolock situation.
sinc ethi sis happening to me so i often i am thinkign of just eliminating that way of oil getting into my intake.
any thoughts?

If you have any room, raise the tip of the valve cover tube up a couple inches . Should solve the problem. Otherwise, with an open vent that motor will probably crap all it's oil seals without a vacuum on the crankcase . You could use an evacuation can , vacuum supplied to one side from the pcv and the other tube to the valve cover .
