My son's work has an 06 Ford - blew the turbo!

They deliever aluminum truck components on an F350 2x4 (aluminum truck flatbed) with a 24' aluminum trailer... . Truck runs on freeway and has been on the job about 6 months. This is the 3rd turbo failure that they have had (however the other two were on older PS 7. 3 liter same configuration rigs. )



Now these guys do not ever let them idle down - when the vehicle stops so does the engine. So maybe nothing would live up to this.....

Probably over time but in 6 months? Plus if you have a turbo with about 100 moving parts I think its more prone to failure than the rest.

The powerstrokes have roller bearings in the turbos. Not so hard on them to turn off hot. The theory is that the oil can cook off the bearing surfaces if turned off when too hot leaving a film and no protection on the next startup. Rarely occurs by the way, its a way over rated threat of failure.



The failures are probably more likely related to the turbine wheel cavitation problems the PS's have. If they would replace the turbos and then change out the inlet wheel to an aftermarket design it would eliminate this problem.



they really are a **** poorly designed engine and eat themselves from the inside out.
