    about a month ago I changed glow plugs in my 6.2d '82 (ac11g). They failed now and the tips fell off sitting in the heads. Need to take the heads off. I followed procedures in haynes diesel techbook. The controller works properly. Is this possible to fry up glow plugs due to improper timing advance? I pulled only 2, the rest fell apart. Is there any reason to ruin the glow plugs due to any other reasons? Don't tell me to go to the shop and buy tool #4747$%&^*! 'cause I live in Europe. Is this possible to set the timing without strange tools?
    And need to know voltage for ac9g, ac11g and ac60g and what's the difference?

    I'm Not sure if you can burn GP's due to improper pump timing. But you can retrive the broken off tips by pulling the injectors and fishing them out. My guess is that you have an electrical problem some where. The difference in the plugs is the amount of power they draw, the older 9g and 11g plug draw more juice and get hotter, whereas the 60g doesnt get quit as hot but lasts longer. My next set of plugs will either LDM's from http://www.usdieselengines.com/6.5l%20Diesel%20Engines.htm

    Or these from Kennedy diesel
    http://www.kennedydiesel.com/detail.cfm?ID=30

    These plugs are both designed to get hotter than 60's and last longer.

    If anyone can shed more light on this please feel free to correct me.
    cheers, rugger.

    Only pull the heads as a last resort! Try and get the broken off picies out of the pre-chambers through the injector holes. I've used small insterments such as hemostats. It takes alot of patiats, but woth it!. Years ago, made a special tool for getting out suck glow plugs. I welded a pair of Vise-grips onto a small slide hammer. It still takes time, but always does the trick. As far as the Chilton manual goes, If they tell you to go jump in the lake, would you? The best investment a diesel owner can make is to buy the factory manual. Yes they are expensive, but worth it!

    For the stuck glow plugs I have seen a split nut work to get them out.

    http://www.toolsource.com

    and search on "glow plug" and you will see it. Sure beats pulling heads!!!

    Also, get the AC60s. Never have to worry about a swelled up glow plug again.

    Also check out

    http://www.kennedydiesel.com

    and click on 6.2/6.5 parts and then Glow plugs and you will see the ones that he made. Never tired em but some people say they are good.
