The bottom end of my 49 216 is nearing the end of it's serviceable life w/an estimated 119K miles on it. The head was totally rebuilt with approximately 19k miles on it.
Gauge oil pressure at operating temp at most all rpm is 7-8 psi. 12-13 psi when cold.
The oil line from the oil distributor to the head was replaced and the valve train fully cleaned out.
It can take 1 to 2 minutes before I see oil weeping out of the rocker arm holes but i get a good steady stream of oil out of the rocker shaft center connector directed back down into the engine. Once warmed up I get a good continual flow of oil to the rockers, so much so that I have been unable to completely stop the various oil leaks I get from the valve cover gasket, especially at the back side (the lowest spot in the head).
The head drains very well so theres very little residual oil left in the head after shutdown.
This has been pretty consistent for 19k miles.
If yours is similar your GTG. if your oil pressure is higher your very GTG LOL.
