Need Help!!!
Hello all,
I have a '85 6.9L diesel truck. Today, I went to change the glow plug controller, and it broke off when I tried to losen it. So, my diesel mechanic told me to drill it out, and use an easy-out to unscrew it. When I was using the easy-out, a peice of metal broke off, that was part of the threading for the controller, and a bunch of coolant came gusing out. It looks as if I broke off a little piece of the head, where the controller crews into. So, does that controller screw into the head, and do I need to replace the head now? Or am I not seeing it right, because it screws into something else? Please help, as I don't know what to do now!?!?!

Ouch! It does screw into the corner of the head. Did a piece of cast iron actually break out? I've never seen one break off before, but I can see where it could be possible. I would've given up when the controller broke and outfitted it with a 7.3 glow plug system. They don't need to be attached to the engine.

I broke off the whole corner of the head. It includes about 1/3 of the threads of the GPC. It is about one inch long on each of the two sides. The rest of the GPC threads are still in the threads on the head. It shows you how tight it was...

How many miles on the engine?
If it was a bunch I would probably change both.
When my controller died I went to a manual switch.
Glow plugs are lasting much longer than they ever did with the controller running things.
As for how hard, I think the shop guide time to R&R both heads in the truck is about 20 hrs.
Last one we did we pulled the engine, took about the same time to do it this way, but it was sure a lot easier on the back. I think it was a better job since we were not standing on our heads to do those heads.

They are heavy and in a very awkward place to lift heavy things. For the passenger side the AC is right in the way.
If you found one with about the same milage on it I would probably try just one.
If you did a reman head I would do both at the same time.

Thanks!!! I'll let you know how it turns out. I figure I'll just do the one side. If it lasts me a few more years then great. As long as I can get at least two years out of it. It really sucks, because the frame has very little rust, and it has a working 12 foot dump bed on it, and a new 4-spd trans as of '96. So I am carefully weighing my options.

I love mine to the tune of 7500 dollars. I just put a complete drop in reman 7.3 turbo in my 86. Truck is in great shape and mine has a 14,00 pound hitch reciever, 9 foot dump, chrome stacks, stainless steel west coast mirrors and 8 foot snow plow. The only two things I want to add is an overdrive unit and a Dana 60 or 70 front axle. The only thing I need to fix is the right front fender has cancer, and it needs a good paint job top to bottom.
Plan on doing a lot of rewiring on the bed and trailer circuits this summer and hopefully fender and paint before winter.
I work in excavation and it is worth its weight in gold to me with the dump, have the springs reworked and it will haul and dump 4.5 tons. Guess i could haul more if I put duals on the rear end.
