Oil leaks at servo / water pumps

[stmotors]

This is driving me up the wall... New Gen tranny (51 plate) oilis leaking at the servo / water pump area... fitted new gaskets, new servo pump, new water pump, but still oil leaks.. looks like oil coming from breather hole on new water pump... never heard or seen this before.. anyone else had this problem or are a box of swan vestas and gallon of 4 star recommended?

Upon closer inspection the Quinton \ hazel Pump had a core plug missing. It must be about 8mm in diamiter, but the new replacement pump had it located. If you have this problem..... check the pump. water pump replaced under warranty and everything A Okay.
