JD 300 diesel

Hi
My 1979 JD 300 is filling my oil pan with diesel OVER NIGHT! How is this possible if the engine is not running? I am stumped. She runs fine. I check the oil after running it and it is ok. The next morning when I pull out the dip stick is starts squrting out mix of oil and diesel (like a gallon and a half). Any help would be great.
Thanks
 
More than likely the transfer pump is leaking into the crankcase. Only other thing it could be is
the input shaft seal on the injector pump.

I've never seen a "tractor title" nor did I know they exist.
The great state of Mass. The guy who sold it to me had it reg. Sohe got a title to it.
