New guy from NC! Help!
What’s up guys? I’m brand new to the site and Duramax’s as well. I’ve always wanted one. I recently bought an 02 2500hd, LB7. I bought it with bad injectors. The crankcase was full of fuel. I drained it and put fresh oil in, just to be able to run it and make sure it was ok. Other than a miss every now and then it ran great. I drove it less than 50 miles as it was leaking into the crankcase very bad. Anyway I replaced all 8 injectors and high pressure lines. I had a return line bolt backed out a good ways, so that was the source of my fuel leak. I got it back together this afternoon. Took me a while to get it primed, but it cranked and ran great for 15 seconds or so. Then started to idle terrible. Really lopey. It didn’t really smoke at this point. So I’m thinking, maybe it still has some air still in the system. So I drove it less than 500 yards and something came loose. It’s started smoking awful, it was a dark gray color. It also sounded like the engine was knocking. I got it back in the drive way and shut it off. Let it sit for a few minutes and started it back up. Again, had the lopey idle, but no smoke and no knock. I idled it up to smooth it out. Then after 30 seconds or so it did the same thing. So I cut it off for a few minutes and got the same results, lopey idle, no smoke. I stopped before i really screwed something up. Any insight to this would be great! Again it ran/idled pretty good before I replaced the injectors. Three of the old injectors were full of crud.
