Mitch :
IMO, that is reasonably normal for a TR, as long as the oil (eventually)
oozes from all the rockers. The engine design deliberately 'meters' the
rocker shaft oil through the rear cam bearing, the shaft is not supposed to
get full gallery pressure. Unlike the main, rod and cam bearings, there is
not a great deal of heat generated by the valve train, nor is there a
uni-directional wiping action, so there's no need to maintain a constant
flow of oil. As long as the surfaces stay 'oily', they're fine.
However, because of the slow oil movement, it's not unusual for the shaft or
rockers to get clogged with deposits on a high mileage engine. (IMO this is
a particular problem with Pennzoil, I wouldn't use that stuff in my
lawnmower !) When that happens, you need to disassemble and clean the shaft
and rockers.
