Okay, I had a leak in the oil cooler line going from pressure switch fitting to radiator on a 98 3.2. After I changed the line, I had a leak seeming to come from the fitting whch the oil pressure switch screws into. This is the goofy fitting that screws into the block and has the line that curves around and connects to the line going to the oil cooler. IS this a one piece fitting or what? It it supposed to be loose? I can spin it around freely when disconnected even though the part that screws into the block is nice and tight.
