Tap for a few seconds is "normal" for these engines ....kind of...
Miles on engine, oil change interval, oil level all part of the equation.
One of my M's 5000 OCI is usually quiet untill about 4000 then gets a little "tappy" in the morning. Oil analysis says oil is good etc.
There was a TSB on this issue, you could go thru and change the rockers/lash adjusters if it really bothers you but it is a fair ammount of work...
At 160k and 140K my M's can tap a little in the morning.....
