There's a pretty pronounced green band on #3, never seen that on a spark plug before. Any thoughts?
By the by, cars been overheating often and running low on coolant, plus the A/C compressor has a tendency to lock up sporadically during turns (fun) and insert any various other DSM problem.
Thanks

I'm gonna check the tension on the pulley after dinner, otherwise I might need a new clutch on that.
Girlfriend raised an interesting possibility, Iron and Pheltsbar (sp) mixed in approriate quantities and fired to approx 1000F produce a greenish glaze. I know where iron would be present, but where would my plug find a silica, and how would I have turned my engine into a kiln!?!

Exactly. That'll be the cause of your overheating as well.

It could be a headgasket but the green is caused by glazing which is basically a lean fuel mixture, or an engine overheating, if the head gaskets fine colder plugs will help.
And Mike do you ever say anything helpful or are you just a dick to everyone who says anything you dont agree with?
Why did i turbo a 420a? Why is your 4g63 smoking in a ditch?

Re-read up on how to read plugs. White or light grey is what you get from lean mix/overheating, not green. Green is 100% coolant dye
