Default 2001 cummins oil leak?!?!

2001 24v cummins
my entire under carriage was coated in oil so i cleaned it all off to find out where the oil is coming from and i think i narrowed it down to the front left (drivers) side of the block right behind a pulley....any help?

Do you still have the factory bottle for crank case attached? It can cause oil to get everywhere once it reaches the fan. Just a thought.

Very popular for the gasket between the Vac pump and timing cover to leak. Mine did, and it looked like a front crank seal leak by the way the fan was throwing it around. I ended up pulling my fan off and running the engine to pinpoint the leak.
