Coming up on the 60k maintenance, and I notice the manual calls for inspection of a bunch of stuff, including engine valves. The rest of the stuff -- brake lines, fuel lines & connections, drive shaft boot, etc. -- seems to be relatively simple or at least easily accessed (i.e., cheap), but engine valves? Taking off valve covers sounds expensive. And, what am I (they) checking for? "Please inspect the valves" could get me nothing more than "Yep, they're there, $250 for labor please."
Why does the owner's manual say to have the valves inspected as part of routine maintenance and what is actually done during that inspection?
Thanks, Tristan
