I believe one or more of my glow plugs are going or gone bad. I have noticed more white smoke when starting. It starts right up, but it blows more smoke than it used to. I plan on getting new plugs, but every time I get the money, something like a winch comes along and puts me deeper in debt than when I started. Am I causing damage buy starting my engine without the glow plugs working properly, or am I way off base with the white smoke issue?
