No don't do that!!!
When you say it's leaking out of the back, you're saying the exhaust side? If that's the case you could probably run it to make that delivery. If it were leaking on the intake side you wouldn't even want to start it because it can run on that oil and "run away" its possible your risking your core though no matter what you do.
