Thanks for the feedback, I am not worried now. By the way, this guy is a contractor/friend of mine and I didn't really have any reason not to believe him, esp because he has 3 diesel Ford pick ups and they all burn oil between changes. He even told me to stay away from any diesel that doesn't burn a little oil because that could indicate a problem. I will probably drive the truck on Monday. It is a 1996 F350 w/ 117,000 miles on and everything appears solid and the original box was just put back on, so it looks great. Biggest concern now is how to address ride quality as he had the stock F350 suspension upgraded to an even heavier rating.
