Help with TR-6 Head Oil Leak

["John F. Browder" <jbrowder@usit.net>]

I have a '71 TR-6 with an unusual oil leak.  I bought the car out of
prolonged storage...almost 10 years.  Has about 60,000 miles on it.  I
flushed every fluid, refilled, and the car ran great, no leaks.  As I have
put some miles on it, it has developed an oil leak that appears to be
between the head and block at back end of engine.

I re-torqed the head and it has slowed the leak (I think), but not stopped
it.

Any thoughts?
