That was my miss understanding, you do not want the feed completely blocked .
I had an issue with an engine that had oil pressure problem once that was intermittent with this style of drop on lifter. It thought for sure it was an electrical glitch. The oil pressure would drop to zero, the engine never would make any extra valve terrain or engine noise. When I would shut it off and start it up the issue would stop, oil pressure would go to normal. I rode in it, drove it, and was just baffled. Sometime it would go 10 miles with zero oil pressure. Turned out the oil filter collapsed, it would register zero oil pressure when it acted up... Apparently this style lifter does not need much oil pressure to work. You sure couldn’t do that with most retrofit set ups, it would immediately be clattering.
