my v8 has recently been having oil pressure issues when im slowing down under about 1000rpm or when i start it normally the oil pressure gauge drops to zero and the light comes on, ive changed the oil pressure sensor because it was leaking but i still have the light and gauge problems and i believe another sensor is leaking oil near my transmission?? any suggestions would be appreciated please.

 

I would suggest getting a mechanical oil gauge to test the true oil pressure. The stock type of sensor and gauge are no where near accurate.
