Without going out to find an adapter to look at, I suspect that is the cooler bypass. Should have a spring behind it.
From Memory Hope this makes sense!!
In the Oil Cooler Adapter there is a pencil size hole with some kind of plate or rubber or something on the opening. Is that the pressure relief or related to it? If not what is that hole for?? Please Forgive the explanation as it's been a few years since I've looked at it!! dunno
