Back to Reality....
I think I've returned to earth! Mercedesrover is completely right. A valve not completely closing was never a suspect in my mind, but worn valve stems and guides leaking an absurd amount of exhaust gas somehow was. If this were the case, all the exhaust valves would just be flopping around in there and blowby would have been the least of Bostonian's worries.
No matter what the cause, it is just as possible to blow a decent quantity of oil out of the filler on top of the valve cover as it is to blow it out of the side-block filler tube since, as Mercedesrover pointed out, the valve cover and oil sump are at the same pressure.
Whew (and thanks)--It's nice to be back from fantasy land. Now where's that embarrassed, apologetic smilie......
