hey guys, i have a problem here. have an 01 lude, recently started hearing a rubbing noise coming from the cam gear side of the engine. my buddy helped me take da cam gear cover off and we noticed the timing belt was going over da edge of the edge of the cam gear and rubbing the plastic cover. after taking the timing belt off, my friend told me to replace the idler pulley on the tesioner cuz it was worn, also replaced the auto tensioner. was good for about a week after, now that it started doin the same thing....what else could it be? everything else is good and tight, and belts are properly adjusted. any suggestions what else too check?
