OK, maybe my saying those that wouldn’t use them is “bull” is too much a blanket and over the top statement. But it applies to some where the cost of something is met with skepticism. See that often. So I’ll ratchet that comment back!
Anyway, I ran em (w/1000 rpm idle) and during assembly pre-lubed an engine prior to buttoning up and can attest that those small orifices indeed saturate the lobes. And I both oiled thru head to shaft and thru pushrods to rocker cup adjusters. So yes it was leak city. You might cringe at that!
And now I’m running direct axle oiling solid rollers with the same shaft and pushrod oiling setup. Oil everywhere. But I only spin to 6200. And oil pressure is good, but you’d still likely cringe :eek:
