Sparky
I think I'm remembering this correctly my engine machinist said on later bbc
with the rear cam bearings oil entering at 9 o'clock (front view) the
bearing sometimes fails and reduces oil pressure to the rear main bearing .
His fix is to drill a new cam bg oil feed hole up from the rear main and
reinstall the bearing with the feed hole at the bottom making it like 427s
were . If you find your rear cam bearing is warn that might explain your
problem . Somebody tell me if I'm remembering wrong
