Coolant/oil intermix;
Top three suspects:
1. Failed oil cooler - the oil cooler is actually a coolant/oil heat exchanger. When it fails, oil and coolant can mix.
2. Failed internal freeze plug: one on each head. The engine needs to be removed to replace the freeze plugs.
3. Failed head/head gasket: Cracked head or head gasket is allowing coolant and oil to mix. Often coolant gets into the combustion chambers. Check the spark plugs for discoloring.
Good luck mate.
