Leo,
Frank is right and Jack Laird came up with a neat trick to help minimize
leakage. Email him for info, but basically he used very fine emery paper on
a glass plate to smooth off a smidgen on the bottom edges of the eyebrow and
then clamped it tightly into position above the rear main bearing cap before
tightening. Paul A. also has a system using JB Weld. I have the paperwork
on that if you are interested...
Cheers!!
Jim
