M998A1 with 6.2, i’ve now replaced 4 glow plugs on the same cylinder.
A popular theory was that the injector was leaking and dripping fuel onto the glow plug. The normal heating cycle of the glow plug was igniting the glow plug and roasting it.
I replaced the injectors with cheapo import injectors.. melted another glow plug. Thought, well, that’s what I get for buying cheap injectors.
I replaced the cheap injectors with Delphi injectors.. melted two more glow plugs.
Start box is operating normally. I’ve metered the glow plug lead to verify that it’s not sending power non stop or anything weird.
Exhaust has a greyish smoke, smells of unburnt diesel. Truck otherwise seems to run fine.
Is it possible the Injector pump is sending too much pressure down that line? Would “turning down” the fuel at the pump be a possible option? Or is this perhaps just a timing issue?
Any thoughts or suggestions appreciated!
