Ok, now I see what you've been talking about

. Yes, they told me it _might_ be that causing a noise, I had two sounds actually, one before this that sounded like it was coming from the timing belt area (which could be this problem you had), then one started this weekend (a loud clicking), which may jsut be the same one getting worse, I never paid attention because I thought it was normal until 3 mechanics pointed it out, so I don't know...
Grr... anyway I'm going to have them fix the valve lash with shims today (damn $600 at best), if that doesn't get rid of all the noises, I'll suspect this. They said they would find the noise and fix it during the belt change later if need be.
Edit: Oh, thanks for all your help man, I apperciate it
