Damaged glow plug threads (1 Viewer)

[gerg]

Has anyone ever experienced reciever threads in the cylinder head that were damaged enough to let the glow plugs shoot out while driving? How did you repair it? Remove head and Machine a threaded inscert? Ideas? This isn't my problem but one I'm helping with.

What kind of engine? Removing the head and fitting an insert would be the best way.

Sure those aren't spark plugs in a Triton 5.4?

It's a 3B. I think replace the head with a good used one is probably the most straight forward but an inscert would work too but then yould have to buy the inscert kit and do it properly which it doesn't sound like something that's commonly done. Well not on cylinder heads anyhow. Not counting time I doubt yould be that far ahead money wise with the inscert.

I thought machinists kept insert tools on hand for jobs like this. Obviously they have to be done properly but why cant it be done properly by a machinist?

I think that would probably the the best way but wonder what the cost would be?

It wouldnt be much $50-$100 maybe if you remove the head yourself. You are going to need a gasket.
I have had a local machinist do jobs like this for me over the years. So long as you dont want it done today and a prepared to wait a few days, its cheap.
Might be a good time to check the head over for cracks and flatness etc.

Yeah, good excuse redo the head. Be easier if this project wasn't 1500 minutes les from me.
