Glow Plugs with Oil on them?
I pulled one glow plug out the other day (replacing the rest today) and noticed that the sheathed filament was covered in black liquidy stuff.....looked just like oil!!!!!! Is this to be expected? What does this possibly indicate? Could it be just carbon build up mixed with the diesel or somethin' like that? I will let you guys know more when I pull out the rest...
