I think I may have fried mine. I accidentally hooked up the battery while the ignition switch was in the run position. I realized immediately as it arced due to the glow plugs drawing current. Ever since, the wait light blinks for about 4 seconds and then goes off. The glow plugs are turning on...

Thought I would give an update, maybe others can learn from my experiences. I got the tip out, the outcome was not ideal but I would say acceptable. Here was the process that did it. 1. Remove injector 2. Put a cotton ball through the injector port into the pre combustion chamber (read this...

I'm afraid to punch it until I get more of it drilled out. Reading other threads, looks like the tip in its whole length won't clear the pre-combustion chamber without breaking it. I'd like to drill out 1/4" before breaking it loose. Here is a picture of the 3/16" jig (top), the 13/64" reamer...

Plan A - regular drill bit. After about 3 minutes of actual drilling time I think I got 1/32 deep, not going so well. Plan B - carbide end mill. Will try this next. Plan C - diamond hole saw. I'm pretty sure this will eat through the glow plug tip (along with the cylinder head)

For those who have successfully drilled out a glow plug element, what worked best? I'm wondering if a long shank 3/16" end mill might be most effective using the hollowed out glow plug jig I made.

I couldn't get the tip out. It is welded in with carbon chunks. I made a jig by drilling out another glow plug with a 3/16" bit and screwed it in, thinking I could drill the tip out without damaging the head. Unfortunately it is really hard to get leverage on a 90 degree drill given the...

I pulled the injector tonight, tomorrow I will try to extract the glow plug tip.

Will it over volt on the other 7? I was planning to put the threaded end back in to seal up. I just need to drive it to my backyard.

Was removing the glow plugs today and got to the one closest to the driver and unscrewed relatively easy, but to my sad surprise only had the threaded body. The element or tip appears to be in the port where it sits, likely swollen. One thought I had was to crank the engine and see if the...
