Dale & John -
Thanks for the replies. And I had forgotten earlier, but I had replaced the valve cover gasket just last year, and after having checked that first - it seems to be OK.
I think I'll now go with the O-ring fix, and see what that does. Hopefully that'll get it done. If not - it's on to the rear main and oil pan gasket...then...who knows.
Thanks again gentlemen.
Dale - any ordering info ono those O-rings you could send would be of great help. I'll be ordering them soon as I know where to get 'em.
Thanks
& God Bless America
(especially the Sailors...LoL)
