Shot it with penetrating oil - broke - 3/8" breaker bar 2-1/2 " Ratchets . Tomorrow go at it with new 1/2" breaker bar if that breaks will heat with acetelyne torch . Anybody got any ideas ? Took one off my other engine with penetrating oil and 1/2" ratchet .
They are tough. You might need a length of pipe over the 1/2" breaker bar and that might break the bar. I usually have a hard time with a big air impact gun. Good luck.
