A former member, nfpgasmask, did an extensive write up on the timing belt replacement, but he hosted it on his personal website and that website doesn't seem to be around any more. I have a printed copy of the write up at home that I would be happy to scan and send to you if that would help.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
-Douglas Adams, Mostly Harmless
