Finally found that my oil leak (replaced the drain plug gasket and oil 5
times) problem is a hairline crack in the oil pan immediately adjacent to
the drain plug.
The plug threads into a thickened (re-enforced) area of the pan and
immediately at the edge of this thickened area starts a hairline crack that
radiates outward for about 3/8 th of an inch. It is possible that the
manufacturer welded this thickened area into the pan and the weld junction
is either failing are developing a stress crack.
I propose to clean the area with a wire wheel and then hit it with the wire
feed welder. Ground strap will be within a few inches, however I will
disconnect the battery just in case. Wife will stand by with a huge fire
extinguisher. Car is up on a hoist.
Removing the pan is the other alternative, but lots of exhaust pipe and
cross bracing in the way. Probably about 2 hours work.
All comments, suggestions, warnings appreciated.
