Thank you. I am glad sites like this are available! I am 68 and have a number of years behind me, working on diesel trucks and tractors. I still listen and learn all I can and am happy to share with others, what I know. I own several diesel trucks and have gotten pretty involved with 6.5's. I have three rebuilds going on right now. My personal truck is a 1993 3500 crew cab, dually. 6.5 with 4L80.
