I am up in Vancouver, BC and finding guys that work regularly on the A4 is becoming difficult. We used to have one of the best in Rob Hess in Richmond but he is out of the biz now as far as I know, please let us know if you find anyone down in Washington as a rebuild will likely be in my future at some point. I try to do most of the peripheral work myself and would pull the head etc...but a complete rebuild is likely something I wouldnt have time for. The guys at moyer marine as well as their website are very helpful for most projects.
Thanks Jarod
