that’s probally a good thing
awhile back I saw a video of someone using a coolant system vacuume setup to suck all the oil out of his engine so he would be certain to get all the oil out. Yes he even capped off the pvc hose. He was able to get quite a bit more oil out….certain to be able to dry start his motor .

That video, ^^^^^^, taught me that our engines have 17 to 17.5 quarts in them when full... which I did know prior to seeing it... Thanks Troy.

Ford 6.7 oil psi
I found a head on another forum about the ford 6.7 oil psi…there was a service manual extract….
min psi at operating temp:
10 psi @ 700 rpm
20 psi @ 1200 rpm
35 psi @ 1800 rpm
measured at the port near the oil filter…don’t know if that is before or after the filter element.
thes numbers are a lot lower than some of the cold startup numbers folks have reported.

Just changed my oil yesterday. Started it, got the truck off the 4 ton jack (I drive the truck up on 4k lb/side plastic ramps and yes, not the best idea but that's why I've been using the jack under the plow frame in front to take the weight off the plastic ramps and also place a 6 ton stand under the front axle >>> the reason I do this is to get the truck up is to make it easier to get under the truck steps and to get the oil pan angled back so more oil drains out of the pan... ANYWAYS...
When the truck was running with new oil in it, I removed the oil fill cap with the FS2500 swivel return fitting to check the flow of the return, as I remove the big FS2500 spin on filter to drain and then re-install it, and wella... the oil was black... which means that when we do oil changes on our 6.7s, there are at least 3 quarts left in the engine that is not coming out unless you were to remove the upper oil pan...

So you drain the FS2500 spin-on while it's running? I always change the TP roll when changing oil and then check the flow at the fill cap with the truck running and it does take a bit to get oil there but I always assumed it was because the dry paper roll I just installed needs to get filled with oil. I don't know how much is left in the engine but it's enough to make the new oil blacken fairly quickly.
^ Totally agree, for heavens sake we have instructions in the manual to not drink the battery acid, so having actual data with a run of the mill end user would cause more problems than anything else. We have idiot lights for a reason.... there are a lot of idiots out there.

based on these numbers…thinking ….run an oil line with a check valve from pan to 12v turbo pump. Then run another line with a check valve to pressure side of my external bypass manifold, which is connected to my oil temp switch port. Put a 20 pSI switch on the motor. This should get me the 10 psi startup with key on before motor cranks…and provide a way for excess pressure to relief thru the 2 micron elements and back to the pan.
when I get my analog transducer monitors…if I don’t like the s actual prelube pressure…I’ll just change the 20 psi oil pressure to a 30 psi or higher.
but, it’s Jan weather in November…26 degrees today…project will be shelved until warmer weather…unless we get a good warm day.
