Might try to heat it one more time to as hot as you are comfortable with. Have cold wet rag on standby, once heated, take the cool wet rag and try to cool just on the EO. Take good decent punch and attempt to move or fracture the EO. I have used this method of heat and contract successfully on taps etc
