I have milky oil going from my Crankshaft Breather Vent into my intake duct, but the oil on my dipstick looks perfect. And my car stalls at idle.

When the head gasket starts to leak it can do so in a small way which is what you have described. Also, if the car engine is not run often and it never gets hot it will do this as well. Here are two guides to help confirm the issue. If the head gasket is okay please start a new thread for the stalling issue.
