Greetings-
what color would the spark plug center electrode be for a cylinder that is maybe burning a little oil? Plugs for five cylinders appear light brownish or white, while the number two cylinder has some coarse med gray deposits on the center electrode. Otherwise, the engine runs superbly wo any indication of oil burning. Color charts say this is a normal color, but since it is quite different from the other five, my suspicions are aroused. Or is this just normal BITOG paranoia?
