| Post subject: | Broken GP tip. HELP PLZ!!! |
Ok guys. I was replacing the GPs and when I took off #2 the tip is broken inside, I believe its been like that for a while as the base of the GP where it broke off looks all carbonized and not as if it just broke off. PLZ I need to know if some one has gotten that tip out w/out having to take the engine apart, any trick to get it out . Help will be much appreciated.

Uh-oh... First thing I would try is having a look down the hole. Do you have a bore-scope? If not, they sell a couple at Home Depot for looking into walls and small holes, but I don't think they are small enough to actually get IN the GP hole... But they will let you see in from the top what is going on in there. two possibilities - If it is still in the shaft, either a vacuum cleaner sucking on the hole OR possibly cranking the engine to BLOW it back out might work. If the hole is cleared... Who knows when it came off, I would try the vacuum trick anyway, and crank it a little too. The top of our pistons is a deep bowl, if this broke off a long time ago it is possible you have already expelled it or it is stuck in the top of the piston. I don't like the idea of expulsion either, it would have to pass through the turbo... Where it probably has gotten stuck against the VNT vanes or obliterated against the turbine's wheel at 80k rpm. None of this is a good situation, IF it is not in that shaft still. But, the good news is - If the shaft is clear, there isn't much you can do other than tear the entire engine apart... And why do that? Could you say for sure when the break happened? As likely as not, the tip isn't in your engine anymore, and you are still driving. |

GP #3 was missing the tip when I replaced mine with the metallics. Was your cel on? A code for that GP may mean it's been like that. In my case, it "passed" harmlessly...lucky me. |

I replaced three, at different times, ceramic tipped plugs and each time you can tell not all the tip was still there albeit very small volumes of material was missing so the engine either stuck some mass in the bowl on top of the piston(s) or mass just went through the events right through the turbo... Now running the metal plugs/updated GPCU ECU flash and hopefully my glow plug problems are over. Good luck to you in what you decide what path to take sir. Roland |

well, somehow the tip is nowhere to be found (miracle I say), not inside the cylinder not the GP hole. Now, that not being a problem anymore (crd ran normal on a 5 mile test), there is another issue probably worse. GP #3 top came off with the inside of the plug but the threaded part with the tip of it still on the head, I was going to try a bolt stractor but it catches on the threaded part of engine head before it touches the body of the GP so I didnt even try. any ideas what to do in this case?

I don't think I will ever mess with my glowplugs after the day you are having! I would try a smaller extractor, or a different set. There are different designs, one of which is the "Grabbit" which has a fairly wide hex body and is not really made for anything set deep in a hole. Black and Decker make a different style that looks like a reverse drill bit, tapered. There are different sizes of that, although I don't know if there will be much to grip with one of those... I'm hopeful for ya buddy. Good luck. |
