Leaking Oil Pan Gasket

You need to get yourself a Chiltons, Haynes, Ford, or other service manual. The oil pan gasket can be serviced in car. But it will require supporting the engine from above. The K-member is then lowered from below. Having a lift may be almost required. And certainly some special tools.

Suggest double checking the source of the leak. Make sure it is not leaking from the oil sender or the oil filter adapter as those items are much easier to service "in the car".
