W8ye, I did not understand why I would eventually see power decrease by this setup, can you please tell me why ?


i think w8ye meant that if its not vented to atmosphere the bottom end of you engine will not get the amount of lubrication it needs . once the pressure equalizes there will be no more movement of oil to the crankcase, which is why the vent is on the crankcase to start with.
