What you call check valves are actually metering valves with a filter (known as drip plugs), metering different amounts of oil depending on the specific location's requirement. For example, the clutch throwout bearing gets less oil than spring shackles. The lubricant used was Bijur Oil which is approximated today by either SAE-50W motor oil, or SAE-85 gear oil.
