    oil check valve 077 103 175B

    Hello all!

    Valve 077 103 175B - the one that stops oil running back from the head to the sump when engine swithced off. Is there a torque figure published anywhere for this item?
    I've seen the thread and borrowed the picture from quattroworld. Crushing it with ARP main bolts is not an issue as i'm using new factory bolts, i just wanted to know whether there is a figure so i don't go overboard and distort while tightening? (the valve body is quite a light duty)

    Many thanks!

    I doubt that there is a torque value. If there is it will be low like 7 Nm or something, i.e. snug.

      Okay call me a liar. Not 7 Nm. Only 6Nm. I didn't expect to find it but I did (item 15):

        Good guess then! I trawled through some of the workshop diagrams online but all the ones I found just showed It but with no torque figure - cheers for hunting that down!
