German Castrol question.....(PICS INSIDE)

oh yeah??? take a straw for example... force a gallon of water through it and time how long it takes to empty the gallon of water.
now get 2 gallons of water and force it through the same straw in the same amount of time. it will require more "pressure" to force that extra water through the same size of straw.
fact of the matter is a higher flowing oil filter will allow higher oil pressure.
now lets say if the oil filter was after the oil pump and the sensor was in between the filter and the pump... THEN hightened oil pressure would be a bad thing, restriction ='s pressure of coarse.
but ****, what would i know 
No. Try plugging that straw at the distal end, but keeping the same force behind it. It will have higher pressure than if it had been allowed to flow freely. See? Less flow, more pressure.

umm... what? lol since when is the oil filter at the distal end of the oil flow? the oil has a clear shot through the pushrods and into the heads and fed back down with gravity.
this all comes back to your logic that a less flowing oil filter causes higher pressure. the sensor is in the top of the block...
You could very easily fix this by answering the question that myself and others already said we don't know. Does the oil go:
pan -> pump -> filter -> engine -> pan
or
pan -> pump -> engine -> filter -> pan
pan -> pump -> filter -> engine -> pan
or
pan -> pump -> engine -> filter -> pan

im 90% sure that it goes pan - pump - filter - engine - pan
the oil pick up from the pan goes directly into the oil pump. then im pretty sure it pumps it through the galley into the filter and then up to the rest of the engine... i could be incorrect though
irregardless. the oil is obviously filtered before the oil pressure sensor.. otherwise i might as well run no oil filter cause its not doing any good anyways

Why would oil go through the engine before it's filtered?
Obviously the filter is in front of the engine.. and in turn, the pressure sensor.
As long as it's all filtered somewhere along the way, it wouldn't matter, of course. That's why. And it's all in the rear of the engine, closest to the firewall, not the front.

PIckup screen clears the big stuff, pump sends the rest through the filter, then clean oil goes through the engine, and pulls deposits/shavings back down to the pan, rinse and repeat. Who knows what kind of crap some people have floating around in their oil pans that hadn't gotten picked up for a few passes.
And also oil does not go through any particular oil passage to get back into the pan, it drains right back down past the crank. So if you want clean oil, you have to filter it before it gets pushed through your bearings, up the pushrods, etc because you can't filter it on the way back down to the pan.
SO it can't really be measured AFTER the engine, it's measured INSIDE the engine, and AFTER the filter.
