    Default High Miles - Looking for tips to extend engine life

    My name is Gus and I need your help! Just acquired a 1994 Chev 4x4 Silverado with 275,000mi. It seems strong but has a rear main oil leak (not major) and trans or drive train noise. Looking for any input that could extend the life of the truck. It does not burn oil, starts every time and will do every bit of 70mph+ when I want it to. I have an OBDII reader and I think this car is OBDI, is it true that I can use a converter cable to read with OBDII unit?


    A little about me I am a Jaguar owner 4 times and produce www.jagrepair.com I know this is far from a Chev truck but we (wife and I) retired to Woodstock Va and found we needed a truck and so that is what I got. I had a car lift (9000lbs) installed in one of the bays in the garage to help me with my articles on Jag repairs and I think I will be using it often with the truck. I can and will turn a wrench when necessary.

    Welcome to the asylum, ABANDON ALL HOPE, YE WHO ENTER WITHIN. Use the truck as little as needed until that noise is sorted out. I run Duralube in all my engines, and their trans treatment in all my diffs, Tcases, and trannys. Some will say it's snake oil, but I have seen a marked improvement in performance, and reliability. This will not give you a new truck, but it should slow down the friction that is slowly eating it alive. Once again welcome.

    Thank you for the warm welcome. I was poking around the truck today to see what I was up against and to make my todo list. I cleaned the TB and cleaned and treated the K&N filter and I noticed a little oil at the intake manifold left side and I think it is coming from the valve cover so replacing them is on my list and along with it the thermostat. I was told that the Trans fluid was replaced and when I checked it and it looked clean. I thought about adding an additive but wanted to see what others felt about doing that. In the past I used BG ATC Plus with good results, I am a big fan of BG products and BG44k.

    Man I would love to have a lift in my garage! But back to the question at hand. I used Motorcote in my ZR2 and had no problems. It is something that now sells at WalMart ( a store you will not find me in) and they also sell it on their website. It is similar to Zmax in that is soaks into the metal to help reduce friction at start up as well as during operation. The other thing I would do is replace the fluids in the Tcase as well as the diffs as you can tell a bit by how it looks when it comes out. Also when take the dif cover off and check to see what kind of metal chips may be present. Also check to see any wear or damage to the ring and pinion. It probably wouldn't hurt to pull the plugs. Plugs can tell a lot about how the motor is running and possibly forcast any future issues. Congrats on the new truck!
    Oh and welcome to the club!!
