Interesting Idea, though you still probably want some other crankcase vent
functional in case the injection ports don't suck enough.  BTW, VERY little
oil, if any, comes out the vent unless there is something wrong with one of
the side seals.  probably best to just plug the oil injection and vent the
crank case.
