I just joined after reading this thread, because I am having a similar issue. I am trying to figure out what is wrong ... why my oil pressure warning light comes on, generally, at some point after engine reaches operating temperature. I intend to post my own thread about this issue, however would pose one question here as related to the pressure valve.

The production date of my 92 E36 318is 5speed is June of 1992. (Is this the plastic one?)

The (mystery) non-return valve looks to have had some changes from the same car produced in may of 92. I wonder if it is plastic and if it could melt... ?  Referencing part at the given pelican link:.  318is (1992-95, from June 1992) Coupe Manual Transmission, with M42 Engine (E36)

I regret having to make an introduction under such dire circumstances, in someone else's thread, so, I'll put this aside for the time being, to perhaps reference at a later time, in thread dedicated to my own situation. For now, I'm hoping to just learn more about these valves.
