Bob , I had the same problem with my 93 4.2 a couple of years ago . The culprit was the head gasket !!! The oil passage from the block to the head is very close to the edge of the block/head. Mine was leaking on the drivers side Head / rear . The oil was then going down the block until it hit the two sensors and then onto the exhaust. superdave
