How have you established that it fills up with oil?

oil should run down past the tappets into cam gallery then sump its either a very blocked up with ****e engine or back pressure is considerable or theres an issue with rockers/shaft and oil is squirting directly up to filler cap

The oil pumped up to the rockers drains back down into the sump by the pushrods.
I can't see how it could become blocked enough to stop the oil draining back. It must be a serious case of crankcase over pressurisation, usually worn/stuck piston rings so compression leaks past the pistons and blows back up through the block, head and out the breather.
It should be obvious if you take the breather off the rocker cover an it does an impression of Ivor the Engine.

Blowing oil out the top is one thing but filling up is another.
Can you feel the pressure if you put your hand over the breather cap hole? It would have to be a helluva lot of pressure to prevent oil draining down and would be obvious.
I'm thinking someone's left a rag in the cam gallery or something daft.
