There are threads on this if you search. However, in a nut shell, you have input shaft seals out in your pump or injector or return line leakage under the valve cover. Or possibly all of the above.

Edit:[b:5529b8b4fb] do not attempt to run that engine with that much fuel dilution in the crankcase![/b:5529b8b4fb]
 
The 4 cylinder diesels have 2 common leakage prone areas: the umbrella seals on the pump driveshaft and the soldered excess fuel return line under the valve cover.
