In Reply to: Found leak---out oil pressure switch up into posted by Greg on November 04, 2001 at 17:54:34:
I had exactly the same problem a couple of months ago. I was worried about the head gasket. My mechanic was planning to use dye to follow the oil trail. I searched the archives of the board and a couple of posts pointed to the pressure switch. Low and behold, that's what it was! A $13 fix and ten minutes labor. This board is great, eh?

The oil pressure switch leaks out the contacts into the rubber connector and travels up the connector to where the rubber part ends then drips down onto the intake runner and etc etc.
