i'm located near tewksbury. and yes, unfortunately the car sounds quite ill. upon further inspection, it almost sounds like the dull chewing on metal noise could be oil getting sucked into the upper intake manifold or something stuck in there. i was considering taking it off to take a look. after watching many videos, it seems that the ticking noise is common among n62s. or am i wrong?

thanks in advance! i appreciate the responses and views. hopefully i can get to the bottom of this as i absolutely love the drive and aesthetics of this car.
