You guys are scaring me! Why on earth would it take you a week to replace the belt? You cut your thumb off, got it surgically replaced and then let it heal before finishing right? I need to change the one on my LX sometime soon, and I really don´t want to hear about it being that hard. I´ve replaced one on a 2.2L legacy and it took me 3 hours.. and most of that was spent double, tripple, quadripple checking my timing marks since the previous belt was incorrectly installed. I realize the belt is right next to the front right fender, but sheesh!
I´ll take the single row timing chain on my 4cyl BMW m10 motor over a rubber belt any day.. mostly because it sounds nice and mechanical, but also because it will last 300K+ trouble free miles and doesn´t retard high rev timing like a rubber belt does. You only need to worry about replacing the timing chain when you´re in the process of rebuilding, so maintenance free is fairly accurate. One good thing about timing belts is the ease of access to adjustable cam sprockets.
