<VV> Leak at the base of the oil pressure switch

[shortle]

Others mileage may vairy but FOR ME a small dab of anti seize on the threads and then I install the sender and tighten using the proper socket and 3/8 ratchet. Maybe I am lucky (I am) but I have never had one leak at the base and my warning lights work properly.
