Erich,
It is normal in automotive practice to vent the crankcase to the carb side
of the air filtern not the atmospheric side.
This prevents contamination of the air filter. Some points to bear in mind
:- Oil vapour through the carb effectivley
reduces the octane rating of the fuel so is best avoided if possible.
Performance auto engines use a catch tank.
Heavy breathing of an engine may indicate excessive wear in the cylinder
bore/ pison rings. Maybe a compression check
might be in order, this assumes your engine is past the "running in" stage.
