Hi not familiar but the obvious answer assuming youve got the right viscosity oil, is theres too much in there, is there a dipstick or a fill level plug?

I think the shaft drive system is being pressurised by the gearbox. It might be that the engine/gearbox vent pipes are blocked causing the whole crankcase to be pressurised which has then blown the seal on the gearbox output shaft.

Either that or you have gearbox oil leaking into the shaft area. Same seal.
