I have a 2008 Dodge Sprinter. Trucks runs great, full turbo

Customer Question

I have a 2008 Dodge Sprinter. Trucks runs great, full turbo boost, for about 15 minutes then turbo stops. If I stop the engine and re start, same thing happens. When I have boost I can hear a hissing sound, not real loud but I can hear it. I am going to take it to a shop but could use advice on how to not buy a new turbo if I don't need one.

Hello, welcome and thanks for asking your question. My name is*****'m a Certified Auto Technician with 28+ years experience. I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

Two possibilities come to mind from the symptoms you describe. The fact that you hear the hissing sound leads me to believe that there is an intake air leak. The first possibility is that one of the intercooler hoses has split and is leaking turbo boost pressure. The second possibility is a faulty Turbo Resonator. Either of these scenarios will result in oil spray in the area of the leak. If the Turbo resonator is at fault you will see oil spray/spatter near and on the brake booster. IF it is an intercooler hose, the hose will be oil soaked as well as the surrounding area. There is one other possibility that comes to mind and that is the Intercooler itself. If it has a hole somewhere the symptoms will be the same....

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert
