After hearing some nasty noises coming from the timeing belt area I took the cover off to inspect it. The belt is in fine shape but it was super loose. When I looked at it with the car running I could see the noise was caused by it flopping back and forth against the idler pulley spring hook! :shock: I removed the spring to check it to see if it was out of spec but it wasn't and then I tightened up the idler pulley to take up some slack. Started it again and it was still flopping so I thought I needed to go get another pulley and spring. Turned it off again and when checking now, everything is tight. :roll: WTF? Cleaned up the cover and reinstalled and it runs great now but should I be worried? Also, could the belt have skipped some teeth? Should I take it off and reinstall at know TDC? This happen to anyone else before? Thanks.
