Any 3.0 owners done a DIY timing belt change?

I was thinking about doing my rocker cover gaskets, pcv valve and oil pick up pipe because I have some oil leakage around the rocket cover gaskets and a bit of oil in some of my spark plug chambers so now I'm considering a full DIY timing belt change as per this guide AudiWorld Tech Articles

Has anyone else done it?

i'm going to take this as a no. Looks a reasonable enough job, if a long one.
