: May have found engine oil leak... any insights?

I may have found my leak. I'm sure I'll have to take it to a mechanic, has anyone had this kind of leak before?

Here are the pics.

Hard to tell from the pics but if it's up front on the drivers side I would guess the oil filter housing o-ring gasket is bad. Requires removal of the alternator and oil filter housing to fix. The gasket is cheap but the labor will be a couple of hours probably.

Thanks! I was able to lift the car a little bit and saw its also a little wet behind there... so, it may be something else. But it is for sure in the area of the Alternator... oi...

Just clean it off real good with Brake Klean to remove the old oil. Now you will be able to see where it's coming from. Could also be a head gasket but that's an unusual area for a head gasket problem.

I've seen VC leaks go down the head and be blown back into that area too.
