I did mine and it was a piece of cake.
Small idler and waterpump bearings were shot (96K) rest were starting to head that way. Saved me a ton of money that I'll spend on a good downpipe.
Definitely recommend doing the oil pump seals while your at it, only added half an hour to the job.
I've been following this thread on nasioc and Meaty has just put up a video on youtube on how to do a cambelt replacement.
Not sure if it's of interest to anyone, just thought it might help some people.
