Physics don't change, but our understanding of them certainly does. Just look at what happened in the 1940's when those wacky physicists came to understand how to split the atom and put a good chunk of the Japanese real estate market under violent reconfiguration. I don't believe for a minute no one has learned anything new since 1917. More pointedly, oil flow/control in an engine involves far more than simple physics.

Actually, oil and flow control IS just simple physics. It's not even the tough kind of physics. The thing that isn't simple is manufacturing.
Making an engine with perfect oil and flow control is 100% possible. Mass producing them is a whole other ballgame. Not only that, but what's required of a race engine is rarely required of mass produced highway engine. The development and application of information is entirely different and wholly separate. But we peons are left trying to make race engines out of highway motors that are built for two things: using less fuel, lasting just past the warranty period.

Engines with crap oil systems, or cooling systems, or other sub-optimal system wasn't designed to be a turd. It became a turd because some wonk decided to save a few pennies by cheapening the design. Using 'novel' methods to reduce parts count, machine operations, or inspection procedures is always the name of the game to cut costs. In the end we get tiny head bolts, small oil galleries, LW connecting rods, heavy flywheels and every other damn thing that blows up as soon as we hit the track.. 'tis the way of the world.
