Oil leak...but where???

I am getting oil spots on my drive and my parking space at work. Not much but is still a leak somewhere

I looked under my car just now and although most of it is bone dry, there is oil right down the centre of the engine underneath. it looks like to is coming from the front of the engine between the sump and the BIG pulley.

I checked my engine oil and that seems fine. i had a power steering leak about a month ago, but my mechanic said it was sorted. there seems to be quite a bit of oil on the underside of the car...but where is it coming from?

The oil seems to be quite clean and not black like engine oil (that has been used of course)

I attach pics to show what i mean

Any ideas??

Hmmm...Pirate.

Nasly leak....almost as bad as the leak in my wallet after my wife and kids get hold of it, but.....................

There only to things that come to mind,

1. Maybe a sump gasket has died and started to leak around the pully area. The air at the front of the engine would be enough to blast it over everything like it has.

2. The seal around the shaft of the pully itself has failed (I am asuming this as I cant see all of the pully and if its attached or connected by a shaft to maybe the crank)

Hope this helps.

Cheers buddy, will check it tomorrow.

Know it cant be too serious as there is no loss of performance or MPG and the engine oil seems to be pretty constant
