904 pan leak

It could any of the above mentioned area's leaking or it could also be the dipstick o-ring leaking and running down on the pan making it look like it's the pan leaking. It's possible it's the pan leaking but a pan leaking as bad as you say is really rare. You need to verify where it's coming out for sure. If it's leaking as bad as you say clean it up and lay under it and watch it with a good light, probably won't take long to see where it's coming from. If it does prove it's the pan leaking make sure and check it for flatness when you take it off. A lot of the time guys crank the bolts down too tight trying to stop it from leaking and they distort the pan sealing surface. If it is distorted you need to lay it on a flat steel bench or good smooth flat floor and using a ball peen hammer tap the bolt holes out until the surface is flat and straight again. The Mopar gasket mentioned above is the best gasket to use.
