Spark plugs stuck and broken
#13
94 s10
Just bought a 94 S10 4x4 4dr with the same issue on the #1 cylinder. Only thing remaining were the threads in the head. Bought as 5/8" screw extractor, attached a 7/16 12 point, 1/2" drive socket and about 2 feet of extensions with a breaker bar going thru the fender well with the tire off. I sprayed it with CRC penetrating the day before and the day of. After a few whacks with a hammer to seat the extractor it pulled the remaining part of the plug out. Worked like a champ, but I also think the cold weather helped by making the steel head contract more than the metal from the plug threads. I never used any heat on it. Soon as I figure out how to post pics, I will

FYI with the head off on the bench after you chisel out the rust around the the thread it will turn out with just a screw driver LOL
