Something else to consider. If you look back 20+ years ALL of these engines have had early issues. What you didn't have 20 years ago was internet that can blow everything out of proportion very quickly.
6.9 IDI had issues with head gaskets & glow plug controllers. Personal computer was just born... The Tandy TRS80
7.3 IDI has issues with the big "C"... lack of knowledge on consumers part for preventative maintenance, people were just starting to learn more about diesel powered trucks.
7.3 PSD had early issues with HPOP resevoir draining back, UVC harness plugs. Internet was in it's infancy with dial up. A high powered desktop was 166 mhz and with 64 mb ram it was smokin'
6.0 PSD comes out, internet is running warp speed with forums like this. Humans are a herd type of animal, love a good fight, picks on the new kid and the **** hits the fan.
6.4 comes out, high speed net is worldwide, if you ain't got a cool vid on youtube, a myspace page, mebership in 6 diesel forums
, a blackberry, a puter with a quad core 3 Ghz processor and 8 Gb of ram and T1 speed internet you are living in the stone age... Remember how long it took to have a video posted all over the place of the truck that was spitting flames out the tailpipe because of a problem with the regen burn in the particulate filter .... IIRC Ford only had a few thousand vehicles sold at that point and only 3 were reported to have had that problem up until then.
Yes there are lemons back there and you will ALWAYS here more about the bad ones than the good ones. It's just human nature , just easier for us to get on a soap box now
and I guess it's time to get off mine
