glow plug opinon....
Looking for your guys opinon I don't have an issue starting my 7.3 in the mornings but as a preventive maintenance I wanted a second opion on glow plugs if I'm going through PM work and find a couple of GP's out of range spec. Should I just replace as required or replace all at one time? The accepable range is .5 to 1ohm on a good functioning glow plug as I undertand right? Thanks for your thoughts....

by a shot i assume you mean starting fluid.....
when was the last time you changed the glow plugs? how long does the wait to start light come on? have you ever changed the relay/controller?

If I was on a tight budget, replace them as they go bad.
Just be aware you may be changine a couple more soon, or then again you may be good for a good while.
As long as the resistance is between .5 and one ohm they are working OK.

If you are using starting fluid to start it, it will start to damage things over time...i even know of a air intake that caught fire because of it. I would recommend replacing your glow plugs if you cant start it when its cold.

if i had a meter that read the low resistance,then i would only change the bad ones.
since i don't,and used the test light method,i opted to change all 8 when i saw 3 where bad.
one or more must have been out of spec(even though they lit up),because it started easier yet again.
so i say,if you have the good meter,then get your $'s worth out of it,by milking the GP's for all they're worth.
just test 'em every other month or something like that.perhaps every month in winter.
