anyone ever blow a turbo oil seal,and rebuild it, only to smell burnt oil?..how long is it going to take to get the burnt oil smell out of the exhaust?.everytime i pull my boat and get the exhaust hot i get this faint "wiff" of burnt oil in the cab.it was real bad right after it happened.ive taken the pipe off the turbo and double checked to make sure its not blowing oil again.is the cat holding it in?.the trucks an 04,no mods,all stock.it runs perfect,its just the smell thats driving me nuts.
