Well here is my mini write- up on these stubborn basterds that i did this week lol This is my first write-up so sorrry if i mess up here and there...
* left side of motor- remove fender well, oil dip stick, air intake, and set degass bottle of to the side a bit to get in from the top.
*right side of motor- remove fender well, remove trans dip stick, and unplug glow plug module to give room to access #1 glow plug.
For me, the ford tool was just a piece of metal to throw into my scrap pile, and the wire trick just snapped the plastic off and I could not get my big fingers around the harness to wrap the wire around tight enough so that was out of the question. So I went in like a mad man and ripped the harness out until wire brok off and it was basiclly flush with the head.. Drilled a 2 inch drywall screw in the center about a 1/2". Then used linemans and once again wiggle and pull straight out like a man mad. 3 off them i used a small hammer and screw driver and chisled the plug out until i saw the rubber oring and got a control flathead screwdriver and just pried the oring out- the remaining harness came out with it... This job sucked and I have not installed the new plugs or harnnesses yet(parts are coming from tousley in 2 days)
When i install them it should be a piece of cake except- use a 7/32" vaccum tubing to slip on the end of the glow plug to so u can fish it down in the head correctly, torque glow plugs to 14 ft lbs.
Also i make up a 3/8" vinyl tubing for my vaccum cleaner and used that to suck and small pieces that may have fallin in the valve train(do not be concerned with small amounts of dirt or metal and this will make its way to the oil filter when operating...
Lastly- use a 3/4" steel copper pipe cleaning tool to clean the holes tht the glow plug harness goes into, use neverseize on o-rings or grease and that should be it... While i was in there i re-wrapped my wiring harnesses with fresh electrical tape and cleaned my fender liners. Thanks, hope this helps with someone that has a stubborn glow plug harness that wont come out
