Name That Leak

[ElNormo]

I've always suspected my car has a slow oil drip, but I simply top it off occasionally (every month or two).

Yesterday, I had it up on jack stands to do a brake replacement. With the help of this forum (and the IRC channel), everything went perfectly. About an hour after jacking up the front end, I noticed an oil puddle under the passenger side, about at the axle. I've attached two pictures.

I don't normally notice any oil on the level driveway, it appears to have leaked only after being jacked up. I'm going to double check tomorrow. Looking at the pictures; however, it looks like the underside is coated in oil. I must confess that I'm not that familiar with the underside of the engine compartment.

Any ideas?

Thanks

Norman
