I found it very "relevant" to this topic. I'm just a truck driver, so it could be my feeble mind.
A video showing how the screens simply restrict the flow of oil, from a guy who builds some of the biggest, baddest, high powered, innovative marine engines out there, is irrelevant and stupid. Or him simply suggesting in the video, that if you run a high volume pump at extended periods of high rpm, to "be careful". And how the proper screen size, is important. Totally not relative to the OP's question.
What are your thoughts about a big block long stroke marine engine turning high rpm, and the crankcase windage trying to push air up thru those screens, while oil is trying to drain thru them? Is there any truth in that, or is that irrelevant as well?
thank you, for your continued great technical insight you, once again, have brought to the forum.

Watching a guy dump a gallon of oil on top of the screens proves nothing other than if ANY filter media is instantaneously flooded it can become overwealmed for a moment.
Tell us about what you read in super chevy about the long arm BBC.

You finish your first ever engine build with 47 people holding your hand along the way? Whats it been 2 or 3 years now? Maybe you should start reading about engines instead of huffy bicycle modifications
I know , alexi from boostpower is stupid. Hopefully he reads your posts here and learns a thing or two from you.

Never said the guy was stupid. Just that dumping a gallon of oil in the valley is not relevant to the question of wether or not to use screens.
You have the emotional composition of a teenage girl MT.

If it was oil with nano technology , it would have flowed right thru those large enough to see thru perforations.
Psst: I don't believe it was the experience of Alexi, it was just the visual shown that wasn't very accurate. I'd like to add that oil temperature has everything to do with flow rate and flowability. A made up word. Ha !

100% correct.the use of a screen in the lifter valley is old school thinking and rarely done these days.think about it.if a lifter breaks no screen is going to stop the damage from the lifter grinding on the camshaft.i actually saw a engine get trashed from the epoxy bonding the screen to the block breaking loose and clogging the oil pickup screen.im not telling anyone what to do but i never use a screen in the lifter valley.
