weird color on spark plug

[seanman]

so i just tried cranking my engine to see what would happen. i have power now and everythings dandy. so my engine cranked over but nothing more than that. so i decided to check my spark plugs, none were fouled or anything, but the lead spark had a yellow brownish tint just where the hexnut meets the ceramic. it was also apparent on another one, but not as much. i've never seen that before, so whats the happens?

[seanman]

anyone?

It's normal, just caused by the heat. Unless it's really bad, then you might need to go with a slightly colder plug.

[seanman]

ok cool. to check if you get spark you're supposed to take the coil pack and spark out and hold it over the cam cover to see if an arc passes right?

[Seishuku]

Yup, that's one way.
