Hello.
Strange tapping sound coming from cylinder 8 area.
This could be a sign of the valve clearance adjustment need it?
It's happened last year and the sounds few days later gone...now is back again.
if is shims, still able to drive or causing serious damage ?
Car runs fine and this tapping sound gone above 2k rpm.

Thank you
