Glow Plug Issues- 300 Tdi
Anyone ever run into a situation where the glow plugs have hung or partially seized up in the bores of the cyl. head? I have #1 and #2 (from the front of the motor) that were real nasty coming out. #3 was fine and #4 wasn’t bad either but never experienced this before. I used anti-seize on the threads last install a couple years ago and was just checking things recently and never have encountered this issue before. Once I did get the glows out, I did notice that these two bores were pretty carboned up vs. what I've usually seen.
Any input on this one?
