I've been hearing a steady tapping sound coming from the engine and I was curious if this is normal operational noise or something else.

I can hear the tapping clearly at idle and it is not exhaust shielding as the noise stops when the engine is turned off. Its also not oil level or type. The car has around 1,400 miles and hasn't been in for its first change yet, so Ester oil isn't a factor.. I also doubt its fuel related as nothing but premium has been placed in the tank from a variety of stations and the noise persists.

I have made short YouTube video (less than 40 secs) of the sound. Before I hit the dealership and make an *** of myself, I'd like to hear your thoughts. Thanks.

I'm alright with you jumping in answering questions. I think that can be helpful. But a lot of this stuff is just being negative for the sake of being negative. I feel like it's going beyond actually helping people. Just wanting to state my opinion, that's all.

Don't you think these members can click and read that thread if they chose to without you jacking every other thread out there...??
