It would have to be extremely restrictive. The amount of oily vapour that
comes out of mine is very small. If there's so little flow rate, there
should be hardly any back pressure.
But, then, who knows what funny arrangement is in there. Is it possible that
the thing was designed with a severe restriction, so that with the emission
controls in place, the sucking from the carbs/manifold would not create a
vacuum in the crankcase?
