Oil in the air filter box

Hi,
anyone suggest the cause.
I was just checking my plugs and took the air filter box off to find quite a lot of oil in the bottom... a few mm in the centre circle where the filter sits... not seen it do that before.
It has been running rich lately ...  the plugs are a bit black and oily....but otherwise runs pretty well.... its a 1990 Petrol 1.9 DG.
Thanks for any pointers..
Stuart

Id guess your oil tower diaphragm has failed.
About 60 quid new if I recall.
