How to remove a seized spark plug and plug wires that will not release from the spark plug either on some spark plugs?
Started to remove the plugs and wires on my 01 Vette Z06. First wire was tough but came off but the spark plug seems to be seized. Moved onto the next plug and could not even remove the wire (it actually ripped completely from the boot). One huge not with this car is there is a metal shield around the boot that slides in the block. Wires release fine from the coil packs but not the engine boots plus having seized plugs. Afraid I might snap one or more. Should I soak them in PB Blaster or what??
