So I just changed my oil, not like I haven't done that before, and now there's a loud rapid tapping noise coming from the top of the engine near the intake manifolds I also changed the fuel filter in the process - is there a chance that a air bubble could have gotten stuck in the fuel system somehow? The noise wasn't happening before the oil change. Help!
