Help with oil pressure fitting

[RS_OBD'oh_2]

Hey, looking to see if anyone knows the size of the oil pressure hole/threads on the B6 head between the disty and the TB.

I've tried 10mm and 1/8... I figure it should be metric. The hex plug (currently filling the hole in the head) seems to screw into the 10mm and 1/8 but the threads dont match with the hole. - if that makes any sense.
I'm guessing it's going to be 8 or 9mm... but confirmation would be great. Thanx.

On a side note.. if anyone has pics of the water lines to turbo (from the t-body or anything else would be a big help too) - I figure I'll have to cut the lines and just place a "T" in.
