I recall the brand new OLDS Delta 88 that my father bought new in 1978 it had three major shop visits before it reached 12,000 mile the first visit was the IP pump failure the other to where do to the cheap metric transmission and the final blow what the rod when throught the block. At this point it was traded and sent to an auction. I also can recall many mid 80's modles that live for many miles. I was too young to drive then but I think this was the start of the diesel toxins that infect my blood even today. The Old John Deere 2 cly helped to.
