Sporadic 'tapping' noise until war.

Thanks for both responses. The oil and filter were changed ( Mobil 1 ) as part of my PPI only 2500 km ago, so should be fine. Of course, I haven't had a repeat of the sound since I put up my post, but a sticky valve lifter was one of my suspicions but didn't know if others have had the problem. I will try to give her a good steady run at moderately hight RPM's tonite.
