530i: Need Help Diagnosing Coolant Leak...

[artguy]

The other day I discovered a coolant leak in the engine.

Before I start tearing things apart I was hoping the wisdom of this group can point me in the right direction as to where it might be coming from and/or what might be causing it.

Here is a shot of the engine. I noticed white smoke coming up from the area where the arrow is pointing:

Here is a shot trying to look down in the area. You can see a slight reflection off liquid down there (circled in red):

Checked to make sure it was coolant by using a paper towel on a long probe. Sure enough...a bright shade of green:

Thoughts on what I should plan for? Valley Pan Gasket?

I already need to replace my Valve Cover Gaskets. Looks like now I have even more to do.

Thanks in advance for your input.

Looks like the tube from the waterpump to the back of the engines O ring is pissed off. Have to pull the waterpump loose and clean the pipe but doable on the front. if you need to fix the rear the intake may have to be pulled but if careful you wont need to do this. Good luck man.

I appreciate the input and direction. I will be diving into this in a couple of weeks, I hope.
