I had my hood open because I was working on something else on my engine and after closing it and driving for a bit I heard a tapping or "knocking". I opened my hood again and still heard it. It actually sounds as if I was really low on oil or almost had no oil at all, although when I pulled the oil dipstick twice the oil level read a little more than full. Any ideas on what it could be? This only happens sometimes?sCO_uhm.gif

Thanks guys,

When do you hear it? Does it only happen under load? Is the car hot or cold? Steady or intermittent?

You did check the oil while the engine wasn't running correct?
