my engine just started ta-ta-ta-ta-ta-tapping! :O its odd.. when you start it up, it sounds more like a knock.. but is relatively quiet and goes away with revs.. after a drive on the hwy, it changes to a loud tap. most noticeable when idling and parked. when you engage any gear, it quiets down but is still there. engine runs fine. no hint of a stall.. oil pressure is about 15 when idle 45 steady on the hwy. no funny smells. no squeaks.. just tap tap tap tap tap tap. any suggestions? the engine light randomly goes on and off as well.
