Unhappy Where is this Tapping coming from???

Here is the deal. My 1990 190E is making a tapping sound from the top of the engine every now and then. The oil is changed on a regular base with the good stuff (Castrol).

Tapping Traits:
The tapping starts and stops on its own, some time over a month apart. The sound is not consistent, loud some times soft other times. The tapping usually last from 10 to 30 minutes when it happens. At speeds over 30 mph the tapping stops, but when I come to a stop it start again.

I know the engine has over 287,000 miles, but I wold like to keep it another 200,000.

Does any one have any ideal what it could be?
