I seem to recall there are TWO senders at the rear of the engine, not too 
distant: one is for the oil pressure gauge, the other for the oil pressure 
idiot light.  Through the mists of memory, I think they're both on the 
driver's side in a conventional layout, on the passenger side if you enjoy 
Brit drive.  But no matter where you are, or what your local driving 
practices, either or both can leak.  Before suspecting something more 
complicated, make sure all the simplest, easiest, (OK, Alfisti: cheapest) 
possibilities are investigated first.
