Seized spark plugs

[Pug0BZ3011]

Just as an update:
Went to crack the spark plugs off and fill them with wd40 tonight after driving it back from work.
As I was preparing myself for a real fight I found the first plug to come undone with nothing more than a gentle breeze, okay I thought don't fully remove it just yet just a quarter of a turn and leave it overnight
Next one was the same, as was the 3rd and 4th.
Turned out to be the easiest set of spark plugs ive changed Was needless worrying.
Next set was put in with some copper grease on the threads and done up by hand (with a final quarter turn on the ratchet) to prevent cross threading.
Well chuffed

The set in my mk2 golf came out dead easy and they were in there for roughly 20 years lol one of those thing that you wonder what you were shitting yourself over lol
