DIY: Oil Cooler (scratch built install, lottsa pics).....>.

Please excuse me if I'm just a little slow and don't understand but I do have a question sort of.

You stated that the sandwich plate does not open up and allow oil flow through the lines and cooler until 180F.
You also stated you drain the cooler/lines during oil changes.

During an oil change, I assume the oil isn't 180F, thus the plate isn't open, so do you do the change, drain the cooler, then let the car idle up to 180F and check the oil levels again and add more oil to account for the increased volume that is not accessible?

If you don't, would you not run low on oil, or does oil somehow fill back into the filter, lines and cooler during the change process?
Would this be any different without a thermostatic sandwich plate if you drained the cooler each time?

Sorry, I admit I have limited knowledge in this area, it just seems to me, that if you drain the cooler, oil has no way of getting back in there until the car is started and the pump flowing, thus you would need to recheck and compensate the oil level after inspecting for leaks. Thus a thermostatic plate would require the car to be started and warmed to at least 180F and do this. Is this correct?
