Ok, I'm new to the forum, but I have been reading a lot of posts and love the site. I have a 1997 hb that I bought new off the lot. It's got 123k miles and hasnt given me much trouble. I love my truck. I want it to last another 123k miles or more so I am planning to do some work on it. The most intensive thing I plan on doing is replacing the timing chain. I have read the detailed posting here on the procedure and while not easy or straight forward, I think it is doable. My questions are, should I undertake this work? What other things should I do at this mileage that I havent considered? Advice of any kind? I should add that I have done some minor work on the truck such as changing the cap and rotor, fuel filter etc. I have changed a water pump on a Saturn (most difficult thing I've undertaken.) Am I about to open a can of worms here? It has a minor oil leak and a minor ps leak. I'm hoping to address those problems as well. I appreciate any and all advice/help I can get. Have a great day!
