Mower has about 30 hours on engine--well maintained---starts

Customer Question

mower has about 30 hours on engine--well maintained---starts right up---
warms about a minute----at 3/4 throttle------suddenly blows enough oil/smoke out the exhaust to fill a room---still runs but rpm drops some-----will suddenly clear and run strong with no smoke----this is without changing throttle speed----this will continue for 30-40 seconds---then smoke for 30-40 seconds----repeat--repeat--repeat---
when it is blowing smoke the crankcase pressure is very strong and blowing out the filler tube---but this pressure goes away when the cycle is not blowing oil/smoke out the exhaust----never have seen a problem like this---what is going on here?
