i got problems guys my truck spits coolant out the overflow, like a gallon at a time when i run it hard. temperature is normal until it loses enough coolant to make the guage bounce and then i usually have to put a gallon or more in the radiator. the crankcase breather bottle is also spitting oil but not a lot. I took the truck to the stealer and they said there is nothing wrong with it and wanted to void my warranty for having an exhaust brake on it. so i keep driving it waiting for it to die :{
