Thanks

Its a cheap part but time consuming fix. Try Scott's suggestion first before attempting to take it apart.

I will check the bolts, but as far as I remeber the leak is above the oil pan, it's coming from above the starter, th eview is blocked by the intake, but it's definitely coming from the rear of the engine.

Could it be coming from that area and dripping all the way down behind the starter?

Thanks
it's at the back of the intake side. The coolant expansion tanks hides it a little bit. It's #16 in this diagram.

Thanks again
stand at the driver's side and strech under the coolant tank for a good look....you should be able to snug up with a 19mm socket and extension........after you unplug it
