318 stroker oil leak :(

If it was me, I'd probably just pull the engine out. If the rear plugs are seaping you'll see it. There are three oil system pipe plugs back there inside the bell that could be leaking, but my money's on the cam plug because it's not gushing like a leaking oil gally plug would. In any event, you can clearly see everything with it out, and if the pipe plugs and cam plug prove clean and dry, you can do the pan gasket much easier.
