This is why I always use NEW glow plugs = maximum possible temperature.
Basic uncontrolled variables with used glow plugs:
* Electrode stress/torque damage
* Glow plug tip degradation pitting/burn off, if the point is eroded = it is junk.
* Glow plug age degradation
* Glow plug brand/manufacture variation
* If you are not comparing each used one to a NEW glow plug, it is easy to make a mistake.
Each cylinder requires MAXIMUM heat for starting...
