oil pressure sending unit
For those who are having the same problem. My leak was coming from the oil pressure sending unit. I had to put the front of the van pretty high on jack stands to get under it to see the leak. It was above the starter and below the exhaust manifold just to the drivers side of the center of the vehicle. I got a new oil pressure sending unit from O'Rielly's for abt $9. Once I had the right socket it was a pretty easy and quick job to change it out. I used a 27mm deep well 1/2 drive socket with a 1/2 drive swivel and about a 6-8 inch extension. I was able to slip the socket and swivel onto the unit and then attach the extension and ratchet all while standing in front of the raised van. Remember to be careful when putting the new unit in that you don't cross thread it. It took me a little while and some patience but I was able to thread the new unit on by hand most of the way and then just tighten a little with the socket. The hardest part was finding the hole to put the new unit into. Be careful and patient and I don't think that you will have any problems making this repair. I spent about 3 hours and $37 and that included buying some extra sockets and swivels; I wonder how much the local repair shop would have charged or for that mater the stealership.?
