Glow Plug and Injector PM
Back again. Got that ole '94 IDI 7.3 350 and thought I'd do some PM type stuff.
Started to pull the glow plugs so I could see what condition they are in and maybe take out the injectors and have them "pop" tested.
First problem was getting at all the glow plugs. No way to pull'em all without removing all those metal fuel lines.
Had to settle for a test light test on each one instead. They seem to be ok but I noticed that in almost every glow plug the plastic insulator over the bullet connector was fried and cracked and falling apart.
First question is this going to be a problem and should I replace the entire glow plug harness?
As to the metal fuel lines. I looked that over a little and found that I would probably have to take them all off anyway if I was going to remove the injectors. But, it looks like the turbo is in the way. Stopped right there.
Second question. Do I have to remove the turbo in order to remove the injectors and if I do, how do I do it? Does the turbo come apart? It's a Garret turbo and my manuals don't say anything about it.
I'll stop there for now. More question to follow, you can be sure. Thanks in advance. Great list.

Mine have almost all the plastic broken too. It does not matter. I replaced a few electrical tip with standard wire connectors, the one you use to crimp two wires toghether, you simply crimp or solder one end to the wire, the other end goes on the plug. You have to use the proper size. As long as you have a good contact, thats all it counts. The plastic is just there to protect from grounding, in case you have some metal parts touching it.
As far as getting your plugs out, I have a 1991 none turbo and i can remove all of them withour disconnecting any lines. I jus undo the line clamps to get some looseness and I use an extension between the lines. It works. But be carreful you do not want to brake the plug. One time I also used a lot of loosenut.
