6.6 duramax vs 6.0 powertroke
looking to buy a '06.5 Chevy 6.6 duramax or '06 Ford 6.0 powerstroke. Seems I get a little more pazzaz with the Ford. Which one has better reputation for reliability?

5.9 let my dad down and it required a tow. Hard to run the Cummins when the lift pump fails. He still has it and is well over 200k miles now.
Not throwing stones at the Cummins, just pointing out that ALL diesel options can and do have failure points.
Some Duramax trucks have head gasket and injector issues, some Rams have Lift pump issues,... Then there is the 6.0.
This is not a motor that you treat like every other motor. You need to carefully monitor engine oil and engine coolant temps, watch for tell tell signs of failure and get it repaired. Change the coolant often and keep a close eye on things. Many 6.0's live happy lives without failure.
IMHO before I bought a 6.0 diesel I would invest in a scan guage II and plug it into the truck on the test drive. Let the truck tell you the story.
The lift pump on your dads 5.9 likely failed long before the truck left him stranded. The CP will still pull the fuel to itself and not miss a beat.
He could have put a cheap low pressure fuel gauge in it and would have caught the problem and still drove it home. The 6.0, most of the time when something acts up, you better find a good place to pull over.
