I really don't know the history. Supposedly the guy drove it 60 mi. to get it to the guy i bought it from, said it ran fine. motor looks in good condition, original. I replaced fuel pump, converted to 12v. Put HEI distrubutor and altinator on it. Swaped the 4:57 diff. with a 4:10, Just rewired the whole truck. Fires right up. Yesterday was it's firt trip longer than down the street and back. Ggot it out on the hiway and went about 12mi. total, seams to be running great, but i had no idea about the potential oil problem at the time.
