I am thinking about buying a 1994 Firbird Formula from my buddy. I noticed it has got an oil leak arond the rear of the engine, but only leaves a small nickel size oil stain on the asphault. Could this be a rear main seal? Where would i need to look to spot where the leak is coming from underneath the car to tell what is bad?

The oil leak could be the rear main seal. It could also be the intake manifold, valve cover gaskets, engine oil pan, or some other item in the rear of the engine. It may take a trained eye to try and determine where the leak is coming from. It may be necessary to clean the area and recheck after driving for while to pinpoint the cause of the leak.
