1971 engine: oil in the timing chest

Hi All.
I removed the rocker feed oil pipe line because I wanted to replace it.
After an hour I found a lot of oil on the ground dropped from the bottom on the timing cover.
It is normal that there was all that oil??
thank you.

From the oil tank. That is a direct feed from the tank. If you want to leave the tank filled use a pipe clamp on the feed hose.

With the timing cover still in place, only if that oil had back-flowed through the OPRV.

Oil leakage from the open timing cover rocker feed connection could also have been oil draining back from the crank sludge trap if the crank had been left with the big ends close to TDC.

After leaving the rocker feed line off my AMR modified timing cover I discovered that the oil pressure relief valve was another source of wet sumping. My bike also left a large lake of oil underneath the bike after a period of time. Now that I have modified the oil pressure relief valve outlet along with the AMR modification I can take off my rocker feed line and get only a residual amount of oil that drains before it stops.

The only other possibility would be leakage through the pump.
