Spark Plugs - What does this mean? Hi all just swapped out my spark plugs approx 15-20k miles on them NGK TR55s.
I placed them as if you were standing in front of the engine, take a look at cylinder 4 and 7, they look pretty toasty and lots of junk on them...
What does this mean on those cylinders?
Close up of 4
Close up of 7
Think my **** is fixing to break? or is there anything I can do to fix the issues?
Any help appreciated.
THanks!

coolant would turn them yellowish/green. they just look cooked, it could have ben detonation ,oil
several things can cause too HOT conditon. i would use ac delco factory plugs, i never had a problem with stock plug
im not saying ngk is bad, i use them for other stuff.
