Sounds like oil emulsion.May be the start of oil cooler problems.
Clean and refill as suggested above.
If it comes back then it's probably the oil cooler O rings.If you're unlucky it's the oil cooler.

Is there any chance there could have been rad weld or similar added to the cooling system?? Id flush the whole system and re-fill and then keep an eye on the header bottle.
