My truck came with a 7.3L Navistar
Diesel Non-Turbo engine. This is one of
the poorest motors ever built. I'm
currently on the second motor(I like
the crew cab room). There is a known
problem with pinholes developing in the
cylinder walls. This causes engine
coolant to enter the cylinder(major
repair expense). This motor is also
poor for hauling a heavy load.
