Coolant Leak Under the Intake Manifold

[samer0214]

Hello Guys,

I know this is a well know issue and has been addressed in many threads, but I believe my issue to be different and would like confirmation before diving into this further.

2005 X5 4.8iS developed a coolant leak under the intake manifold in the form of coolant evaporating and dripping under the car.

Thinking that it's the common know issue with the valley pan cover or crossover pipe under it, I removed the intake manifold, only to discover a ton of coolant on top of the valley pan cover itself, and a broken Y fitting that joins 3 small coolant hoses. My dilemma is, that I'm not sure if the Y fitting broke while I was wrestling the intake manifold out, or whether the problem is really with the valley pan cover.

So the question is: Is there supposed to be coolant ON TOP of the valley pan cover itself (in the valleys of the valley pan cover)? If not, then I'm golden.

I have attached 5 photos:
- 1 showing the coolant on top of the valley pan cover (there was quite a bit more there, but I removed most of it)
- 2 showing the actual broken plastic Y connector
- 1 showing an intact connector and associated hoses (BMW P/N: 17127509967)
- 1 taken from realoem.com, showing the hose. The hose goes from one side of the expansion tank to the 2 cylinder banks.

Any help would be greatly appreciated, as it would save me a lot of time and grief!
