Oil leak, help ID this part. Pic's attached
I'm not sure of the name for this part, it is leaking, I have to figure out what to purchase to reseal it. It is directly below the oil filter housing.

Thats the oil pressure test port... you can get just the black seal and use the mb locktight sealant around the edge.. let it dry along as you can overnight is perfered because that port seesfull oil pressure..

I got the expansion plug from the dealer, part # 1120150630. I cant seem to find any other information in alldata. Does any one have torque spec's for the 2 torx and allen head bolt?

I measured the reverse torque, the torx broke lose 12 and 13nm, the allen head broke lose at 19nm. I torqued the 2 bolts back to 13nm and the allen head to 19nm. It is leak free so far. I couldn't find the torque specs in WIS.
