Can you shock it loose?, using a specially ground blunt (about 70 degrees)
1/4" chisel. Its all about getting the angles just about right and using a
club hammer rather than a light weight one, so that when you do get the
angle just right (so it digs in, but doesn't skid or dig a big chip out)
It'll mangle it more but I've rarely failed with the right approach, which
might even be almost at 90 degrees to the one you would want to use, e.g.
in-plane tangentially, from the side. Whether you will damage or crack the
housing area is another matter. Work a good notch into the edge at a
sensible compromise angle first (so that it wants to turn it but also
doesn't want to jump off either), gently, then when you think its deep
enough to take a good well directed blow, thump it pretty firmly with the
club hammer.
A 11/2 - 2lb club is always preferable, as it can be controlled much better,
doesn't require swinging, and uses mass not velocity - they also usually
have noce short handles. Don't use a soft mallet (Thor style) - you need a
very sharp concventrated impact straight up the shaft of the chisel style
tool - which can be brought over here, made for this job. Maybe Snap-On do
one.
You may not know when you have actually lossened it -so check after you've
landed a good blow that doesn't skitter off.
Make sure you've got a new drain-plug before you start.
Alternately, drill it out staright up the middle - dead accuarte with an
1/8" drill and slowly go larger throught the number series drill range - you
might thenm have relieved the stress on the thread and can either deform it
or drill the thread out totally - but you have to know what you're doing to
avoid wrecking the female thread in the housing.

unservicable. It's pretty "round" and I could not remove it. I suspect that
the previous owner or his mechanic has been draining the oil using that
larger "pressure relief" thingy, since I don't think it's possible that the
proper plug has been removed anytime in recent history. Given the plugs
recessed nature, I have not been able to get a hold on it with any of the
usual tools of ignorance...I've probably worsened the situation.
