Glow plug problem
I have a 1994 7.3 IDI factory turbodiesel.
I just replaced the glow plug relay, and am starting to replace the glow plugs.
What procedure should I use to get to plugs 5,and 7?
Plug 7 is burned off at the top of the glow plug, which is how I managed to get it loose.
I really don't want to remove the turbo unit, as there was alot of difficulty
assuring a good flange fit between the turbo,and down pipe by the company
that installed my Banks Powerpack system.
These are the original plugs. In perusing this site I've learned of Autozones
stock being equitible with my need.Will I have start problems if I only change the six plugs I can get to? By the way my truck has only 97K original miles.
Thanks,
James

get the new plugs from autozone, ONLY USE THE BERU/MOTORCRAFT glow plugs!!
any others and you will only have problems.
to get the 2 rear plugs out, i used a combination of 1/4 drive ratchet and a 3/8? wrench.
blow the area around the glow plugs off real good with air before you start to ensure nothing falls down into the cylinders. i also use a shot of pb blaster and let it work for 1/2 to 1 hour before starting. work the plugs out easy. if they get tight, give them another shot of pb, and run them in some, then try to take them out again.
remember, patience is the key here. if you only replace 6 or 7, than the bad plugs will not be in the circuit, and the new plugs will get more voltage, causing them to burn out faster.
and a helping aid in reinstalling them is to use a dab of neverseize on the new plug threads. this will make then way easier to remove when you have to do them again in 15 years.

like i already stated, patience is needed to do this job. if it gets to you, walk away before you hit it with a hammer.
cause the hammer will only leave a dent you will have to fix after the glow plugs are installed.

Everything worked out OK,on replacing glow plugs.
No.5 turned out to be the hardest one to get in,and out.
Removal of glow plug relay helped.
To remove ,and install no. 7,required using a 36" 3/8 extension
and approaching it from the drivers side,and squeezing under the turbo unit.
Used never seize on new threads.
Truck starts almost instantaneously!!
No band aids needed.
