Or.... rather than mask the problem, you could pay the $80 to have your valves adjusted for you.

If you would rather, get out your 10mm socket, a flat head screwdriver, and a socket to turn the crank. Go buy some feeler guages for under $10 and adjust them yourself. I'm not sure what the spec is for your motor, but I'm sure that somebody here does, or you could look it up in a manual. The whole process from popping the hood to shutting it again should take you less than 45 minutes.
