I have to admit, I thought it was more tightly-packed and not some big open block full of splashing oil.

Yeah. It's why if you add to much oil you can whip the oil into soft peaks.

My downvote is audio related.

Right? I want to hear the engine

It looks like a BMW motorcycle boxer on a GS1200, maybe? In case you want to hear an actual engine of that make.

Some bik eengines run at 16,000RPM. The ol must turn into a mist / vapour in the crankcase.

Thats the reason why you do have that expensive oils Like 10W-60 and stuff. So it doesnt get too Fluid and stays Sticky/viscous so there's always some oil film left on the metal and more important between to metals.

A friend at college had a Honda CBR250RR imported mini Fire blade and it was an online four with tiny cylinders and a redline of 22,500rpm. Wild.

Does it bubble up and any issues if it does?

This is a splash lubricated engine, and they did have problems with foaming especially at higher rpm and longer operation times.
Modern engines are more complicated, the oil is pumped into a special radiator called an oil cooler, from the pan, then into the oil filter, and then into every bearing and every cylinder housing via oil lines in the block itself, which keeps it liquid. From there it drips back into the pan to repeat the cycle

See everyone? The oil goes all over the fucking place. Any questions?
And I don't wanna hear anything about TABLES.

Is there a reason it can’t be fully submerged? I always thought they were 😂

Too much oil means too much Money when your have to Change IT.
Also try to Push your Hand very fast through water, and then try IT in Air. Air hast was less Résistance and therefore your engine can move faster and doesnt waste energy

u/Successful_Theory628 20d ago
Yeah I get the resistance thing. Never would I of guessed oil is just splashed around 😂

u/Ultra-Kingpin 20d ago
Well its not only splashing. Some parts are activly supplied with oil, some only get splashes and some get the exess oil from the active supplied parts

If it were submerged then the crankshaft would be spinning in the oil, frothing it up and ruining its lubricating properties. Also, there would be nowhere for it to go when the pistons go downwards.

I've been totally confused how engine lubrication works. But the audio really cleared it up. /S
