VALLEY PAN LEAK OR...?????

[kipp]

First of all, a million thanks to whoever wrote this DIY procedure:

Without it, I would not have been able to this job myself. There are invaluable tips that get you through some very challenging spots. I might add to it, if anyone is about to do the job and wants to reach out to me.

HOWEVER...much to my horror, my X5 (2003 4.6is) is still leaking coolant. I used Permatex ultra black gasket maker and was very careful when making the gasket for the valley pan cover, and replaced my water manifold gaskets. I can't imagine its coming from either of those spots...or could it? How easy is it to screw that up?

Does anyone have a clue as to where else the coolant could be leaking from? God forbid I didn't get something back on correctly. Doing the job again is unthinkable.

I'm finding about a half cup of coolant (or less) on my garage floor. Its definitely coming from the back of the engine.

Any feedback? Thoughts? Advise? How should I go about trying to pinpoint the source?

Cheers
