Do you remember if the car was burning white or grey smoke? Did it feel like it was sluggish (while accelerating?)
There are countless things that could lead to coolant and oil to mix, head gaskets, piston rings, cylinder walls cracking, ect.. The next step in my mind would be to do a compression test and hope for the best!

Head Gaskets in M96 engines never fail. 2000-2001 heads crack easily. Sometimes they only leak when up to operating temperature. Sounds like this is Clueless problem.
Coolant in the oil reduces lubrication so IMSB deteriorates. Good time for pressure check & maybe head rebuild!
