6.0 tea kettle
I recently purchased a 2004 6 liter knowing all the possible issues associated with the engine. I bought this truck in November with 71k on the speedometer. Tomorrow will be the third time its been to the dealer! I originally took it in for an oil leak and coolant loss. The first time they replaced all intercooler hoses, metal coldside, egr quick connect hose and crankshaft sensor o ring. After getting it home I still had an oil leak, loosing coolant and the tea kettle noise when coming to a stop or shutting it down. I took it back and they replaced the rear main seal and an egr valve gasket. I picked it up Friday and when I got home it started whistling again!! The coolant level in the degas bottle is about 1 inch from min at operating temp. By the way its not running hot by the factory temp gauge and my mileage keeps going up everytime I take it in!! Any ideas????
