Common Oil Leak Sources
Didn't find anything on this with a search. Saw a couple things about replacing the oil pan gasket. Also remember reading about the low oil level sensor possibly being a leak source.
The wife's 525 is leaking oil and a general inspection doesn't seem to pinpoint a source. What are the usual sources? How have you located the source? I've not used the UV dye thing and I (surprise)don't have a black light on hand...
