Removing oil galley plug

Kroil probably won't work if it has never seize on the threads but it
can't hurt to try. If it's really stuck it's probably faster to pull
the prop and ring gear than to mess things up trying to work around
it. Flying long enough to get the case fully warmed up may help too.

Thanks for the offer, but I'm in Wisconsin. Getting anything "straight on"
to the plug is going to require pulling the front engine baffle, and even
then the ring gear may be in the way, so for now, it's going to wait while I
finish the rest of the install and collect more insight on the problem.

BTW: I can't remember if you're one of us from Sacramento or not. After
our initial failed attempt to remove the plug we took it to a guy who
teaches and lives next to Sacramento Community College Aviation (at
Exec Airport). He used the EZ-out from his fly-in driveway.
Email me if you want his info.

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.

Not NeverSeize but pipedope, but I tend to agree. Another trick that
comes to mind is a large American Beauty soldering iron applied to
the plug, getting it hot enough to disrupt the pipe dope. (The iron
will not melt the case so that's no worry.)

You are better off heating the crankcase area with a heat gun and
turning the plug with the Allen wrench. Heating the plug will just
expand the plug into the case, whereas heating the case will expand the
aluminum away from the plug.

Or a corollary might be to run the engine long enough to heat the case and
then apply ice or dry ice only to the plug.

I had a real tough plug to pull once. I JB welded the allen wrench into the
socket
and it cane out with little fuss after massaging the case with a heat gun to
250f
measured with my trusty IR temp gage.........

There's a trick that I read about on the web for removing broken steel studs
from aluminum engine heads where you find a washer with the same interior
diameter as the stud, use a TIG welder to weld the washer to the stud, then
weld a nut to the washer. Use an impact wrench at the lowest setting to
turn the stud out.

I have done this...last ditch effort...ran the engine to warm, iced
the allen wrench/plug, (it was a "socket" allen wrench) twisted with a
"T" handle to equalize torque...

It came out...

Heated the plug with a torch, the J-B let go, allen "socket"
salvaged...

I wouldn't reuse it.

You'd think so, but what you are doing with the iron is two things:

a) Trying to overheat and destroy the pipe dope. (Then drip in some
Kroil...)

b) Breaking the bond between the plug and case.

Many a time I've gotten a bolt out by heating it orange with the
Ox-Acy torch. You'd think it would make life worse, but...

[Obviously, you do not want to torch the aluminum case.....]
