My oil pan is over flowing with Diesel fuel. It is also coming out the main front seal.
Anyone had this problem?

if it coming out the front seal it is in the oil pan,you might have a leaking injector line?????Tell us more...
Could it possibly be coming from a lift pump or high pressure fuel pump and migrating to that front seal location? (I'm not familiar with these component locations on the FL120.)
Have you checked fuel lines and secondary filter for evidence of leakage?
How long did it take to fill your 'oil pan'? (Is this a drip pan placed below your engine?) Did this all happen after a short run or have you discovered it after a long period of not looking there?
Is your oil level rising in the engine?
this sure sounds like the lift pump. A ruptured diaphragm in the lift pump would cause both problems, air in the fuel lines and allowing diesel to get into the crankcase.
And I am going to make an ass out of myself for "assuming".....
But as I understand it, the Lehman 120 has it's own oil "sump/supply" that needs to be changed every 50 hours. If you have not been doing this, it is likely the reason for your lift pump failure.
It is also the reason why I wouldn't own a bilge full of Lehman 120s....that would be 5 oil changes if you include the generator!!!!!!!!...Ain't nobody got time for that!!!!
The oil in the injection pump needs to be changed regularly. A few ounces, takes a couple mins. The lift pump is lubricated by the motor. The failed lift pump is probably the reason for your air problems also.
