Check your owners manual. Theres a requirement to check the clearances at 60,000 miles. At least there is on my 09. At some point they might eliminate the check because
In actual operation this check is almost never done and its rare to hear about a problem. But as the valves wear the clearance will become less and if it gets small enough the exhaust valves will burn. Sometimes the clearance gets bigger which isnt as bad but will make the engine noisier.
