      Hey all, I'm reassembling my motor and have a question about the Oil Non-Return Valve PN: 022103175

      The part itself fits into the cylinder deck hole and sits there with an O ring, inside of the valve there are threads, I cannot remember when I disassembled it if there was something inside those threads,



      Should there be something inside this threaded valve with outer o-ring?




      When I go on ECS I can find the similar 12-pt screw part, but it states it doesn't fit the MKIV R32

      taken from a different VR6 (not 3.2 24v) thread






      The Bentley Manual states to torque it to 5 Nm (44in-lb):

      Any information is much appreciated!

      I believe my engine code is BJS

      I believe I have found the answer to this question which is, there is no screw type part that threads into anything (Threads most likely used for removal if needed)

      Speculation: Perhaps on the older VR6 block/heads they used this screw but came up with this valve instead.
