While tearing down my project 6.2 I ran into some bad news with my glow plugs. Two had been sheared off by the PO when he pulled the engine, which I had planned to pull with an easy-out.

But more concerning was that one of them had also a missing tip. There was nothing left to fish out of the chamber, the whole tip is MIA. I am trying to avoid pulling the heads since the block has only 100k miles.

Most of the older posts I've found focused on fishing out what you can. But it isn't clear just how detrimental it is to the cylinder to have a GP tip banging around in there. I'm sure the textbook, leave-nothing-to-chance answer, is to pull the heads and look for damage to the cylinder wall.

Is there anyone out there that's willing to say this happens all the time? Broken tips tend to find their way out the exhaust valve? Life is too short to lose any sleep over this little matter?

Any help is appreciated.
