Valve Clearance in this generation

The bad news.
Changing valve clearance requires special tools. This is not a simple matter of turning an adjustment screw. It requires removal of a precision-machined disk-shaped shim, and replacing it with another shim of a different thickness. You buy ($$$) the shims from the dealer.
The good news.
You'll probably never have to do this. It is necessary after major engine repair such as grinding the valves or replacing a camshaft. The factory maintenance schedule does not call for periodic valve adjustment. All it says on the subject is in a footnote which says "If valve noise increases, inspect valve clearance."
