Leaking oil pressure switch should present itself as oil dripping from the a/c compressor as it is directly below the switch. Also you may have the oil pressure indicator light come on at idle speeds then shut off as rpms increase. Mine eventually failed and was dripping oil at a high rate through the connector. Use a deep well 13/16 socket or equivalent metric. A little tough to get at but can be done in 30 mins. Get at it from the engine compartment.
