Default green tint/coolant on spark plug?

Hi All,

I have always had a misfire when i first got the car about 6-7 months ago. I changed the plugs in December, but it still misfires a bit - so I am thinking something might be up. I checked the plugs, there is a bit of oil on them due to a valve cover gasket leak, but I also notice a little green tint on the electrode and threaded part of the spark plugs. Is the green tint due to coolant passing through the cylinders or is it something I shouldnt be concerned about? I am not overheating, no coolant in oil, no smoking, but i have been losing some coolant from the expansion pack by the radiator (but noticed the cap wasnt on tightly) - i really hate to think it is a blown head gasket!! I will have to do a compression test to confirm.. any ideas? I also added mystery oil to gas tank and crank case, as well as seafoam to gas tank and intake manifold.
