Which kept you more busy, the s***ty engine or the s***ty way they crammed it in there so you couldn’t work on it?
Well in the late 80's it was glow plugs,injection pumps and wiring. Then they had a recall on all 460 powered ambulances for catching on fire. I went to a school to do those and did all the ones in Mississippi. Those took almost a year. Then comes along the 7.3 diesel, good lord at all those problems, early on it was injector orings,then it was injectors, IPR's leaking and filling with oil, ICP's causing engines to die, fuel heating elements shorting out and blowing the main fuse causing engines not to run. The way they crammed a 7.3 in an Econoline is a totally different scenario. Now they are trying to sell a pushrod V8 gas burner that they had for years (460) but discontinued because overhead cams and turbo's were supposedly the way to go. Now you have to pay 2,000.00 extra for a fuel injected pushrod gas burner (7.3)which they discontinued in 96 or 97. IMO they should just have modified the (7.5) along the way. The 6.0 and 6.4 diesels were another clusterf*** all together.
Fuel leaks were horrendous after the extra low sulfur was mandated by the government. Fuel filter o rings,fuel pump diaphragms were the worst. Also the fuel return line orings leaking and injector pump governors sticking causing dieing on 6.9 and 7.3 non powerstrokes. The low sulfur diesel is dry compared to the earlier version causing rubber to shrink and lubricated parts to stick. That is why diesel additives were popular.
