not really its the engine doing the miles so you had better change it when it says really a risk of snapping valves off in the head is a big expense,i have changed them before they are easy to do unlike people will lead you to believe and the belts are not expensive approx £40 for a pair which is alot cheaper than valves pistons and cylinder heads do whats best for it mate and it will serve you well.:)ADAM
