Coolant in intake manifold (N62)

Hey guys,

First post here, have been active on Xoutpost but hoping to reach a wider audience. I have an 04 E53 4.4L N62 with 125,000 Miles on the clock and have had coolant leaking for the past month, no codes no rough running. I took the throttle body off as I was going to check the expected culprit of the crossover pipe running under the intake manifold and I found this. It's the first time I've noticed the inside of the intake manifold with a green coating. Is this a symptom of the crossover pipe below the intake manifold or is it worse like a head gasket?

Coolant in Australia is a fluro green colour

Hopefully you guys/gals can help

Could try some Permatex before you reinstall.

That's the normal color of the inside of intake manifold. Mine looks the same.
