Agro1,
My Windsor has had a leak since I bought it. It recently got worse, so I had the seal replaced last week. Mine has a one-piece seal that you get to by pulling the flywheel. In the process, the mechanic detected a potential leak in the
oil pan gasket, so he replaced that too. Now the leak is even worse. I drove it down to Southern Automotive to redo everything. I'm running Mobil 1 5W30
synthetic oil. It will be replaced with 10W50.
