My 98 Lexus LS400 runs louder than normal when accelerating. New timing belt, /new valve cover gasket. New 3 way exhaust piece installed. Lexus dealer cannot seem to pinpoint it. They said there was a very minor exhaust leak. What could it be?
When in park the car is extremely quiet. Has new timing belt, valve cover gasket. Lexus dealer said there is a very tiny exhaust leak somewhere but don't think thats it. Does not mater if the car is warm or cold. Its been months and nobody seems to know the answer. Its driving me nuts, what could it be?
have the same problem?
