Was cleaning spark plugs today for regular maintenance during an oil change. As I do periodically, was using a thread chaser to clean up the threads for easy spark plug installation / removal. On my #1 cylinder, I screwed the chaser in too far and it went past the threads. Now, as I try to back it out, it is trying to cross thread. UGH!!!
I fought it for over an hour, but it simply will not come back out easily. So, tomorrow my plan is to "force" is out. My hope is that it will come out, but anticipating my threads to be toast.
How hard is it to replace the heli coil on a Lycoming IO-540? What tools are needed? Is this something I should hire an A&P to do for me? Any advice would be appreciated.
