Found it pretty crazy that after 1k miles I had this much oil. Is it normal?

I don't.....1,000 miles is countless hours with several thousand rpms. the actual amount of liquid / gasses that get put back into the system is so tiny...it has zero problem being burned of during normal operation.

only when you dont burn that off, and collect it hour after hour, mile after mile, do you then see accumulations of this liquid.

perception is much worse then what is actually going on here. if it were a problem.....every single manufacturer would have a factory catch can system.

these catch can companies are creating fear as a marketing tool to collect money from gullible consumers.

I know for a fact Porsche 911 have it. I have even an OEM part number, if you want to check it.

Most manufacturers do not care and do not use catch cans, because problems will arise long after the warranty period and most second (third /fourth) owners never will tell the difference (how the engine should perform).

They are beneficial... but they are an additional maintenance item that most consumers would not tend to appropriately, which would result in even more issues. That is why they are not included on most factory cars.

Especially on forced induction engines, there is gong to be piston blowby into the crankcase. This pressure sends oil misted air through the PCV into the intake and into the combustion chamber where it is burned. The burning of oil leads to buildup in the combustion chamber, piston heads, valves, spark plugs, etc... as well as the catalytic converters, and oxygen sensors. As this buildup occurs over time the engine becomes less efficient, then has various issues like stumbles or hesitation, then one of these parts fail and needs to be diagnosed and replaced... just perfect for post warranty repairs at the dealership.

Not really. It's the intake system creating a vacuum that pulls the blowby into the intake system thus the cylinders. That's why the PCV (Positive Crankcase Ventilation) hoses are connected to the intake manifold. Not to mention the EcoB has two different PCV valves one on each side of the valve covers.

There is no need to measure our knowledge of the force here. Ultimately we agree, vacuum or pressure... oil ends up in the intake and combustion process... and that is not desirable.

And here is another dose of reality:

"In May 2017, just after completing its 1000-mile break-in period, our Raptor vaporized the 60-mph mark in 5.5 seconds and bulldozed its way through the quarter-mile in 14.2 seconds at 97 mph. By June 2018, some 39,000 miles later, it added 0.5 second to both milestones and lost 4 mph from its trap speed. In the wrap-up test, the truck needed an additional 2.5 seconds to reach 100 mph. Some of the Raptor's horsepower, it seems, had disappeared as quickly as seven BFGs and 2850 gallons of gas."

My guess would be the truck has fouled plugs from all that blow by. The good news it can probably be fixed with a few sessions of techron, a fresh set of plugs, and a catch can. ;)
