Is this a problem? I replaced my glow plugs yesterday and 3 of them didnt look like the other 5. Three of them are damp with fuel smell, not oil i dont believe im thinking fuel. Does this mean Injectors are going or......? I am up there in mileage so i just want to know what im in store for. Truck runs great. I had a CEL that was P0380. I replaced the module and that wasnt it. It was the glow plugs. Any info will help. Thanks.
