Angle looks right; all the plugs were tight to remove; this one is the worst so far.
I will wait to remove the other four until I have run the engine enough to warm it a little. Maybe the goo or whatever is making them tight will soften and the threads in the head will expand some with heat. The plugs aren't stuck, I can move them, just tight enough to be scary. They have been in there a long time (too long-they're burned up); I know the PO, but I doubt they remember the last service the car had.
