The sound of loose change rattling around underneath your engine’s cylinder head cover(s) is most likely a result of not enough engine oil or a whole lot of loose valves. In most cases, it’s easiest to release and reset the timing belt’s tensioner instead of trying to figure out whether or not the right amount of tension’s been applied.Ĭlicking or Tapping From Inside the Engine A droning sort of humming sound emanating from underneath the cylinder head cover(s) is a good sign that the same guy who overtightened your alternator belt installed that timing belt. Tension up that timing belt too much and, unlike an overtightened accessory belt, you can cause all sorts of expensive damage inside that big box of pistons and valves. Inspect whatever belts are wrapped around things like your A/C compressor, power steering pump, alternator or water pump for excessive wear and for too much or too little tension.
