I just bought an 81 chevy with the 5.7 diesel. everything works and its super clean. Not only did I pay $700 for it but its a one owner with 44,000 miles on it. The only issue I have is I cant find any fluid capacities on it anywhere. Does anyone have a link where I can find the oil capacity or does anybody know off-hand? Btw I know this is a [censored] engine so please dont knock my purchase. I was on a tight budget.
