Trying to install a block heater on my Branson 5520H. Unfortunately the factory that day must've been short staffed and called in Zeus to install this block plug.

I've tried my bolt buster induction heater to heat the plug and surrounding block, I've hit it with PB Blaster and let it sit several times. I've used a 2.5ft breaker bar and extension, and I've used my 1/2" drive impact wrench that can usually take off tire lug nuts.

Can anyone think of anything else? I'm not crazy - this plug is threaded and is supposed to turn?
