A gerotor style oil pump draws oil from the crankcase through the suction tube and delivers it through the block where it enters the oil cooler cover and pressure regulator valve. When oil pressure exceeds 517 kPa (75 PSI), the valve opens exposing the dump port, which routes excess oil back to the oil pump.

I believe you mis-read your own evidence. How else can the oil get through the block except via galleys and passages? I've been inside enough engines to know how an oil pump works.
As for the contaminates that are poured in via the valve cover, if you read the article it explains that those are caught on the outside of the filter, as designed.

"Filters do not need pre filling either. Another myth."
I guess Cummins recommending the filter be pre filled is "Another Myth" ?

Keep in mind, the oil cycles from the pump, through the galleys and bearings, then the filter before returning to the crankcase. The filter is the last point to get oil on startup.
And if a tiny sliver of silver foil is poured in the valve cover, where does it end up? Those that would pour it in the filter could just as easily pour it into the engine it's self.

A gerotor style oil pump draws oil from the crankcase through the suction tube and delivers it through the block where it enters the oil cooler cover and pressure regulator valve. When oil pressure exceeds 517 kPa (75 PSI), the valve opens exposing the dump port, which routes excess oil back to the oil pump.
At the same time, oil is directed to a cast in passage in the oil cooler cover, leading to the oil cooler element. As the oil travels through the element plates, it is cooled by engine coolant traveling past the outside of the plates. It is then routed to the oil filter head and through a full flow oil filter. If a plugged filter is encountered, the filter by-pass valve opens, allowing unfiltered oil to lubricate the engine. This condition can be avoided by frequent oil and filter changes, per the maintenance schedules found in the owners manual. The by-pass valve is calibrated to open when it sees a pressure drop of more than 345 kPa (50 psi) across the oil filter.
The oil filter head then divides the oil between the engine and the turbocharger. The turbocharger receives filtered, cooled and pressurized oil through a supply line from the filter head. The oil lubricates the turbocharger and returns to the pan by way of a drain tube connecting the bottom of the turbocharger to a tube in the cylinder block.
CAUTION:
Two different styles of J-jet piston cooling nozzles and nozzle mounting fasteners are used, depending on engine build date. The two designs are NOT interchangeable. One design uses an all metal piston cooling nozzle (1) with a fluted mounting capscrew (3). The second design uses a plastic nozzle/body/locating arm (5) , and a metal nozzle tip (4). The second design nozzle must be used with a banjo bolt (6). When replacing piston cooling nozzles, it is important to replace the cooling nozzle mounting fastener with the same type that was removed. Do not intermix both designs in the same engine. Severe engine damage can result if the two designs are intermixed.
Oil is then carried across the block to an angle drilling which intersects the main oil rifle (3). The main oil rifle (3) runs the length of the block and delivers oil to the crankshaft main journals and valve train. Oil travels to the crankshaft through a series of transfer drillings (one for each main bearing) and lubricates a groove in the main bearing upper shell. From there another drilling feeds the camshaft main journals. J-jet piston cooling nozzles (1,4) are supplied by a separate oil rifle. Plugs are used in place of saddle jets when J-jets are used. Crankshaft internal cross-drillings supply oil to the connecting rod journals.
Another series of transfer drillings intersecting the main oil rifle supply (14) the valve train components. Oil travels up the drilling, through a hole in the head gasket, and through a drilling in the cylinder head (one per cylinder), where it enters the rocker arm pedestal (3) and is divided between the intake and exhaust rocker arm (1). Oil travels up and around the rocker arm mounting bolt, and lubricates the rocker shaft (2) by cross drillings that intersect the mounting bolt hole. Grooves at both ends of the rocker shaft supply oil through the rocker arm where the oil travels to the push rod and socket balls."
good point but oil path from sump to pump to filter...what ever pours from valve cover ends up in sump into filter theoretically .
my point in all this is people are worried about a dry start after oil change, so they take 1/2 the intake apart to change a filter and be able to pre fill it.
Is it really necessary? If Cummins or any engine mfg was worried it would be law of the land not just a recommendation.

The techs at the dealers go thru the small cut out in the fender to mitigate risk when changing oil.
Yes , and they do the finger method, don't know where this taking the intake came from, but it sure isn't done that way by the people that do it every day. I fell prey the first two oil changes until I finally got smart :B
So far this a pretty short discussion ,ought to get on a Cummins forum, it will go one for days, and who knows how many pages. Same old ,same old fender well or thru the top. Pick your poison both are pretty awkward .
Well said...
I only got 5k miles on my current load of oil in the sump and I'm getting the itch to turn a wrench and drain it. I drain the sump and the filter in parallel. Pre fill the oil filter (yes I'm a pre filler) spin the oil filter on hand tight, install the drain plug, add 13 quarts (3 gallon containers and 1 quart) drain used oil back into containers and at ~20 minutes I'm cranking the big PowerStroke up and rolling. :B

Pretty much all the youtube videos I've seen show the "through the side of the wheel well method", and it's looks pretty easy, the only issue is getting the filter OUT without spilling oil everywhere. That's why many drop it down into a zip lock or other plastic bag to minimize spillage. As to the out the top method, just seems to be personal preference to me.
Here's what I would look into.

Anyone that would put a Fram filter on a Cummins needs their head examined!
