6.4L - Faulty Turbo Chargers
It’s a fact that a diesel engine functions very differently from a standard gas-powered vehicle. Diesel engines require specific tools, and technicians require specific training in order to correctly service these engines to provide years of reliable performance.

Turbo failure on the 6.4L Powerstroke is a very common problem.
Some come in with broken fins and others come in with considerable shaft play. At the end of the day, they were just a bad design, unless you’re looking to make a race truck!
o The most probable cause we’ve been able to come up with is related to the regen process the truck goes through to clean its DPF. More than likely we suspect that during the regen process too much diesel enters the oil system via the cylinder walls. If you’ll remember, when your truck enters the regen process it injects diesel into each cylinder on its exhaust stroke. If too much diesel is put into each cylinder and not exited in the exhaust stroke, it is picked up by the oil rings and then enters the oil system. This thins the oil out. Between the thinner oil and improper maintenance, it creates a bad scenario for the turbochargers as the oil can’t balance the turboshaft correctly because the oil isn’t thick enough to do its job.
