LEAK 1: VALVE COVER SCREW Because I hadn't done it since coming back from CA, I had the oil and filter changed. There were some drips from the oil pump. I tightened everything on the pump proper. Then I noticed that the screw holding the heat shield, that also retains the valve cover was not tight. We'd left the shield a little loose to position the fuel pump lines. I tightened that screw, but just enough so I didn't see threads.
QUESTION: I'm a little apprehensive about how much to tighten the valve cover screw where the heat shield mounts. What's the guide for doing this?
Thursday I drove to Seattle. I started to experience some slippage. A lot by the time I got home.
As you can see, the interior of the housing has a lot of oil. The little reservoirs in the top of the oil pump casting were pools of oil, obviously coming from above, the valve cover/heat shield screw. I wiped that all down and tightened the screw a bit more.
I pulled the carpet and checked for leaks from the tranny cover. All nice and dry. I added the dust cover to the breather screw, now in the correct right rear position.
REAR MAIN SEAL: I washed the clutch of oil figuring I could make it to someplace to replace the rear main seal during my trip to Monterey later this week. I ordered a pan gasket and rear main seal today (Thanks to Olson's calling me about my email) and it will arrive Tues or Wed, (a couple of Packardians recommended George Potter's son Vintage Underground in Eugene, Oregon. I haven't called him yet, because I may cancel my trip altogether. There is work to be done on the house that may need my supervision.
So oil is getting into the bell housing and on the flywheel and clutch. A lot. I still have that valve cover to deal with, but the rear main seal can be a problem and there's no way to check it without seeing it.
I took oil out of the filter canister so I can add Blue Devil sealer to the oil before I leave and see if that helps by the time I get to Eugene. I may add that tomorrow and do more driving to see if leaks persist, and especially if I can trace their origin, leaving only the main rear seal as the culprit.
This whole thing kills me, because the car ran so smoothly to and from Seattle at freeway speeds and has so much power.
