Unless you have a hoist or a pit save yourself the hassel and pull the motor. I've done 3 pan gaskets @ work. First you have to remove the cross over pipe. Then raise the engine about an 1 1/2". Remove the pan bolts and let the pan drop to the cross member. Then you have to remove the oil pump & pick-up tube from the motor and set it in the pan. Then remove the pan by gently prying it out. I also recommend getting a one piece rubber gasket and using Right Stuff to stick the new gasket to the block and slide the pan back in. When my pan gasket goes I plan on pulling the motor, even though I have access to both a pit and hoist. Either way you go about it you're looking at alot of work, but with the engine out you can clean and paint the engine.
