Now that it's been started, I have no idea exactly what to do. I don't think you have to pull the engine to get the oil pan off, so I guess you could try to pull the oil pan and clean everything and put it back on. I think I would try to use an external pump and an oil flush product to clean the oil system before putting the pan back on. If you circulated the flush with an external pump and the oil pan off, you could also watch the top side and see if the flush is getting up there. Here is the real problem though. The seals in that motor are so old, they are going to leak within a month. Oil will then pour out the back of the motor and probably the front too and will run directly on the exhaust headers...this may very well catch your car on fire. This did actually happen to a friend of mine. If it's set for ten years, the rings may also be stuck and so the best thing is to pull the motor and tear it apart, clean everything and put it back together. That's the only way this car is going to be reliable again after setting that long. Definitely do not start the car again before changing the timing and balance shaft belts and fixing the oil problem. You probably already put excessive wear on the bearings.

Good Luck
