I did open the valve cover while running like you: it squirts all surprisingly nice. So I'm not worried about valve/screw (top) region on the original setup/parts. But I did remove some carbon from the valvetrain prior to that, if I remember well, since mine used to overheat. I don't trust swivel foot too. I don't really take Hoover mods seriously, bcause if you increase oil flow somewhere, it takes away some pressure from the galleries, it may unbalance the oiling system "too much". But some experienced guys know what the're doing and how to "compensate" for each every mod.
keeping things clean is important for keeping things cool. so it looks like you're not running swivel feet? if so, you're not missing out on anything really special
Hey Scotty I ran my all original factory beetle engine with no valve covers and made several videos. Conditions: All factory original engine. New oil, valves adjusted to .006" engine hot from a 45 minute drive. Some 1500 rpm, held mostly at 2000rpm, and revved occasionally to 3000rpm. How much oil came out of the rocker-arm assembly ? One drip per rocker, once every minute. Sooo .. after 5 minutes ... I seen ... maybe 5 drips of oil per rocker. So ... after 5 minutes of 2000 rpm, with the occasional revv to 3000 rpm ... I may have seen 20 drips. And this engine runs great ! We did an evening cruise afterwards .. and put on about 75 miles. Conclusion ... Vw Air cooled heads are 999% air cooled ! The only available oil flowing hrough the head is 1000% for lubrication. I can post the vidvo on Samba .. if you wish. Thanks for digging so hard .. to prove the truth. Cheers
thanks stove. why not post to youtube? make it private and share the link with me? - i'd say the factory knew a thing or 2 about how to keep oil temps under control and cool the heads and vw sure as heck didn't do it by spewing oil into the rocker box as you have now seen with your own eyes on your own stock engine.
It doesnt take much resitance to stop oil flow. The guides always wear out and its a flat motor so improvement is worth the effort. The stock rockers are offset to theoretically cause the valve to spin for longevity. That causes a side loading on guide. Does the valve really spin much? Intake guides can suck in too much oil exaust runs hot and dry. Intakes and exaust need to be handled differently or intakes will carbon up on backside and exaust will not lube up enough and guide will fail quicker.😊 thanks, i trust vw Darrin mine are centered. Exaust has better oil flow than intake. I cut the threads to hole on the rocker so oil could pass easier. Hoover mods can help or go too far. The elephant feet have larger foot but ya gotta get oil to it. The swivel feet are smaller and might oil but its a gamble. The stockers work and are cheap and last with no worries.

Hey Scotty

Sooo .. after 5 minutes ... I seen ... maybe 5 drips of oil per rocker.

I had some bad luck with those swivel foot adjusters.
The balls kept rolling over.
i've read many years worth of forum postings on many many forums about these devices and that is an uncommon but not unheard of problem.
