Spark Plugs - What does this mean?
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!

No...white smoke.
I was reading online and it appears the crust means burning of oil and or fuel additives during normal combustion. Ash fouled...is what they call it.
Wonder why only those cylinders?

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.

Spark plug replacement what I got here is camero 2002 ss convertable no problems 86,000 mile time to change the Spark plugs you think. do I go OEM AC DELCO AC41-985 OE 12571164 gap 0.05 or do I go best choice BOSH 8S4505 Premiun class platinemin fusion no gap or then their is performance ACCEL A35p526s . Got good long life from OEMS will I have the same from the BOSH ??
Don't hear too many good reviews on Bosch plugs.
AC Delco or NGK are the way to go. If you want them to last longer, get the iridium. I went with AC Delco 41-985 and they are good.
Most LS1's burn oil without failing.
