yeah the cheat i use is simply a way of not having to beg borrow steal, or heaven forbid "buy", a timing kit and the method i described earlier is a much simplified version of the process, and it is true that you should check belt tension after using this method and adjust if necassary. as far as belt life goes, i replaced mine with a "gates" belt which are among the best, but even so i will be changing it well before the recommended replacement interval, probably around the 40 thou mark. this method isn't a bodge and like i said earlier, what i wrote earlier is a much simplified version and therefore i wouldn't expect anyone to give it a go just armed with what is written above. the method is very effective and i know of a good few mechanics who have used it, especially on obscure cars that are difficult to get timing kits for.
