03 Dodge Ram Diesel Weird Noise
When I shutoff my truck it makes a weird noise almost like the engine is releasing pressure. does anyone know what this would be?

If its like a air rushing or whisle sound thats a turbo leak. not uncommon to split a hose, if the turbo has a waste gate it maybe sticking open. :Wow1:

If you hear a squeak that is Normal....... If you hear a air spoooooooooosh that is quick but say 1 to 2 seconds then you have a leak. You need to do a pressure test on her and see. The boots that are connected to the Intercooler ( Large Air to Air Radiator on the Front of the Truck ) are known to blow off or have a loose connection / cracked boot.........Boost

My 2002 1500 4.7 is making kind of the same sound. When I shut it off it wll make a vvvvtt sound and it will do it several times about 2 min. apart for several hours. It is in the right front area just behind the headlight . It sounds like a heater mixture door losing vaccum sound. And I know mine has all electric switches because I had to replace my heater core. any help on this would be greatly appreciated.It's not affecting the performance ,but I don't want it leading to some type of a failure down the road. Thanks
