HI own a 1994 E-150 Econoline conversion van with a 5.0 liter engine. This vehicle has 99,440 miles on it. When taking off there is a brief chattering sound that occurs that can also be heard as the vehicle shifts into overdrive and occasionally while maintaining speed on level road. Could this be the timing chain rubbing against the timing cover?
