Gentleman, and I use the term loosely !
When it comes to replacing glow plugs, what are the best for the 1994 IDI Turbo F 250 ? and should I replace only the bad ones or all?
FYI Just took the wife and kids to the grand canyon on oil ! it was an inexpensive blast !
I also went to see Dave but he was at his out of state shop :scare2:
My wife never even knew it was my plan all along to see him......guess we will have to go to the south rim next time and check with dave to be home.

I got a quote from a diesel place $ 490.00 to replace all the plugs ! :argh:

When in doubt replace them all..... cheep insurance policy ... and peace of mind..

motorcraft or buer glowplugs only. they do cost around 10 bucks a pop. but with a factory turbo setup i can have them changed in around an hr.
