I'd pull them and send into the fuel shop for calibration/rebuild.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Rob Posted March 27, 2011 Share Posted March 27, 2011 Hi Rob Have tried previous to remove injectors but with not much successThey seem to be stuck in the head solid got 2 out of 6 free any hints?Thanks JoeHi Joe, someplace within the last month on this site there was a thread going about a gent that had stuck injectors in his DM series truck. There are special tools out there available to force them out but I would soak the injector hole cavity with a penetrant oil for a couple of days to possibly loosen them. When reinstalling injectors be certain to coat the outer body with an anti seize paste prior to installation so they don't do it again possibly.Here's a quick link to get you started. There are about three threads pertaining to this gents problem, and solution.http://www.bigmacktrucks.com/index.php?showtopic=17304&st=0&p=70649&fromsearch=1entry70649Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
