For those who have installed oil temp probes in the forward oil galley of
their Lycoming engines, how did you or your A&P remove the 1/8" NTP plug?
I've got one that is stuck tight and I don't want to booger anything up
trying to get it out. I've heard horror stories of people having to drill
them out because they are stuck but I'm wondering if an impact driver could
be used without causing any damage to the case.

Any experience or thoughts would be appreciated.
