DUDE,...SOMEBODY buy her!!!!
I paid 1500 for my 85 e250 same engine/trans with 125K on her...changed the orings on the injectors...fluids...just changed the leaking rear heat coil..its a DREAM to drive her!!
oh..and the turbo I added helps...there not much other than cavitation that will kill that motor...(well..maybe over 15psi of boost will)..
veg oil on those is EASY...filter it to 5micron...let the water settle out over a few days (skimm the oil off the top...)...dont add more than 75% veg to a tank of diesel if its colder than 50* at night...and ROCK it!!
