I just bought my first diesel pick up a few weeks ago. It's a 2006 F350 6.0. I'm loving it so far. I had read all about the issues with 6.0s and knew what I was getting into. There was the white residue on the degas bottle, and the wrench light would come on at freeway speeds, so I knew what I had to do. The second day I had the truck I tore into it to replace the oil cooler and egr cooler. Once I had it tore apart I found the egr cooler was brand new so I left that alone and replaced the oil cooler. I added a coolant filter and switched to a EL CAT1 coolant. It runs like a dream now.
My future plans are to do a 4" exhaust and a cst programmer with a custom tune. As for the truck a 6" lift, 37x12.5's on 16s. This site has helped me a ton with the knowledge I needed to get into this truck. Thanks.
