Im gonna move this to the TU section but
It could be head gasket as a worst case scenario but potentially you have a small leak in the oil-water heat exchanger.
For a test Id drain the whole coolant system and refill it with new coolant and bleed it properly and see how it copes.
Was it full of coolant when you checked?
Is it pressurising the coolant system?
Is there mayo under the oil cap too?
Is it down on performance ? (go and test it against the book 0-60 time)
