When I was searching for a good Ford diesel mechanic to stud my truck I found a gem of a shop, Pasadena Diesel. A father son team that I believe can pull a 6.0 apart and put it back together with their eyes closed. They even do their own machine work and decked the heads right there. There prices are fair and as far a customer service, well you feel like family. They work on all types of diesel engines but it looked like the Ford was their main business. If you are in the Washington/Baltimore area I would highly suggest contacting them before going anywhere elese. If anyone wants more information or their phone number feel free to PM me.
