I got an OIL LEAK!!!

[funcar@lr.net (Bonnie E. Muscavitz)]

ok, here's what's going on.  I noticed an oil leak the other day, so today i took my 88 16v rocco to my mechanic.  He said that the leak was comming from either the oil pressure sending unit, or the oil temp sending unit.  Here is my question.  As you are looking at the top of the oil filter housing, there are 2 sending units on top.  Which one is which?  the one that's leaking is the one that is towards the front of the housing.

thanx,
