Just bought a metal ladle for 50p from Wilkinson's, cut the handle down, drilled a hole in the stub of the handle, and bolted it on under my 106 so it sits under the one spot that it drips oil from and catches the drips. Hopefully the motion of the vehicle and the air rush will tend to prevent it from getting full. Ah, lovely, lovely bodging. :-)
I tried some of that pour-into-your-oil seal conditioner but it didn't seem to help. And I can't be arsed to try to find and fix the leak on a 500 quid car.
