Welcome to the site !!
If you look at the parts fiche , you will see off to the right side a shape of the case and bolt holes with numbers , if I am reading it correctly it is part # 12 (sealing washer)and #34(bolt) .....

As far as tightening , on engine bolts I always just "snug" them to what I feel safe with , I have always felt with all the oil on the bolt and in the threads , it gives a false torque reading , same goes with the long bolt for the oil filter , I just "snug" it to what I feel is tight enough .....
, Only one's I actually torque is the head bolts , engine mounts , etc , but not case bolts .....
