I have a 1983 300D-T that hasn't had its valves touched in probably over 30K miles. Should I get on it and do it? If so, I'd be doing it myself, so is it a hard job to do? I'm trying to get my fuel economy as high as I can get it and I heard from someone on here that frequent valve adjustments help. Thanks for the advice

Alex
