Okay, I know this is diesel 101 stuff, but: Can having one or more bad glow plug cause your engine to smoke - even when the engine is warmed up?
I believe I may have a bad glow plug, because the glow plug light sometimes takes between 3 and 5 seconds to come on when I turn the key to ignition position. When it comes on, it stays on like normal and I can start the engine, but it may take a second try. Prior to the unusual g.p. light activity, this engine started first time every time. Last evening after dark, as I took off from a stop light, I noticed that the vehicle was producing a significant amount of smoke, and I don't think that it normally does. (83 240D) Brian 83 240D
