I have a 2013 f350 with a 6.7 power stroke diesel engine with 48k miles. The air filter has been changed 8 times. Yesterday Ford gave me the news that my engine was taking in dust through the air filter box and now the engine is a complete loss. Loss compression in 3 cylinders, and spun two connecting rod bearings. Dirt was found in the air pan. dust was found through the intake system after the air filter. This vehicle has been in oil fields most of it life. Has anyone ever experience anything like this?
