hey guys, just curious if anyone has any experience with timing belts..
a few months back, mine broke and i had to tow my car to the mechanics (silly me took it too my local mechanic, i wont next time) At the time i didnt know what was involved with it, i thought it was a simple thing and i thought my mechanic would be more than capable of fitting a new one..

im currently doing a automotive mechanics course at TAFE and i took it in there for my teachers to have a look at because i could tell my timing was out (car pings sometimes, lack of performance, quiet obvious this was the prob as it only started happening once i had the belt replaced), we checked the timing and my teachers told me it's out a tooth...

now, i dont really wanna take it back to my mechanic to do coz i dont think he would do a much better job than before.. is this a really difficult thing to do..

what i really need to know is it possible to make this a D.I.Y job, how complicated is it too do? because im contemplating doing it myself if its not extremely difficult..

please help guys, any comments/advice or anything will be a huge help

cheers
