My mid 60's Case 530CK has the diesel 188. While inspecting the valve train I observed all the push rod ends do not have a tiny hole where oil leaks thru. You can see a iny spot in the center end of the push rod yet it's definitely not a hole. The service manual describes that oil travels through 1/8" hole in rocker arm to groove in adjustment screw and then through tiny hole in screw to lubricate top of push rod. I expect oil dribbles down outside of push rod to lubricate bottom end of push rod and lifter.
As for valve seals, Instead of an oil seal under keepers there is umbrella type valve seals under valve spring cap. I'll take a photo today and post it. I read a certain amount of oil should get into valve guide to lubricate valve stem so just want to be certain correct seals are in place.
