Diesel Bombers - Newbie to Diesel

Hello to everyone and happy new year! I have owned this 1989 6.2l chevy silverado since 1996. Came with 150,000 on it and has been a work in progress ever since. Am too cheap to trade it in and admit defeat, so I have been doing a lot of repair myself and in the process, learning about diesel engines. Every month brings a new problem of some sort (usually another part breaking down or wearing out), but I have been persevering and have a better truck than when it was first bought. Hope I can find some answers to whatever happens next from the board. Thanks in advance.
