blowing chunks and grabbing porcelain
I have read the history of the IDI and the Ford - IH relationship and there was a timeline that went with it for changes to the platform. I cannot find that anymore (maybe looking too hard?). I am trying to find out when the 6.9 engines went from pressed in piston oil jets to bolt in ones. They were pressed in 1985, bolted in 1987 (until they changed to 7.3), but I do not know which 1986 had. Looking to pick up an engine, possibly, if the answer is as desired. Any help?
