92 and up had the 6.5 turbodiesel if I am not mistaken.

THose had a electronic driver on the IP that would overheat and die.....thee are aftermarket heat sinks that prevent this from happening....the IP's on these are the definate weak point. THe 6.2 was normally aspirated but had mechanicale IP's and did not have this problem.
