I looked in the TToC thread but did see anything but it seems that there was a diagram showing the oil routing through the engine. I am curious if there are different ports that could be used to read oil pressure and possibly get different readings.

More specifically how/when the port on the oil filter adapter gets it's oil and what get oil pressure after this port.

A single main galley runs from the front of the block to the back of the block, Kevin. The top port feeds it on the aftermarket, and OEM oil cooler deletes. There are taps off that main galley that go up to the heads to oil the valve train and timing chains. Ford was pretty crafty on the 4V castings and made a single casting that could be used on either side of the motor with the proper oil redirection plugs either added or removed. I am not too familiar with the two and three-valve castings, they may be similar.

as far as the oil filter adapter area last year when i pulled the heads off of my terminator i remember trying to make heads or tails of it because i wanted to pressurize my engine with oil before vehicle install and before startup and didn't want any oil coming out of the threaded filter area. in the attached pics you can sort of see the threaded caps i installed which contained the oil while i was pressurizing it.

the oil comes from the pump through the "lower" port of the adapter boss on the block. then after filtration it goes into the "upper" port in the block which feeds to the block's main oil gallery and up into the heads. factory oil pressure sending units tap into the upper port (post-filter) side.

i was suprised to learn that the oil coming out of the oil pump first goes into the outer circumference holes of the oil filter first, and then through the filter media, and then out from the center of the filter and then up into the engine. for some reason i had always thought it was the other way around.

in this pic you can see how the oil pump feeds directly to the "lower" port of the adapter boss. this is a nemak block

On my 2V with Cobra Iron Block: is there a port I can tap into that lies between the crank oiling and head oiling or even after the head?

My turbos are fed from the oil filter adapter so it looks like this port is before the crank. To fix the oiling issues I had with oil getting into the downpipes and intake pipes from the turbo seals, I designed the turbo oiling as a return system just like a return style fuel system where the oil psi to the turbos is limited via a regulator. Feeding the turbos is a 1/4" od line from the adapter then a larger line returns excess oil back to the oil pan. This setup has solved my issues of oil getting past the seals but I would prefer to have the crank get full oil pressure if possible, so I would like to tap into a port after the crank gets oiled if possible.

To my knowledge, there are none on the front of the block that is not covered by the timing cover. Try teeing off the pressure line going to the block from the oil filter. Place your oil pressure regulator in that line, not in the main oil feed line. It will have no impact on the engine oiling.

This is the one I'm using. Is this the one you're thinking of?

I didn't think you still had an original OEM adapter, Kevin. I thought you were using one of the aftermarket units or this OEM /aftermarket from Ford, which is no longer available.

The port you are identifying in your photo would work well as the input to a pressure regulator to lower the oil pressure the turbos see. The impact on the engine oil delivery would be negligible if measurable at all.
