Take a dipstick out and let a drop of oil on white napkin, then post a picture here.
It is not easy to judge the oils, while you are saying your oil level is not changing? Also put napkin over oil fill hole with engine idling and see if it staying.
Generally the only way coolant can get to oil pan is bad head gasket.

i think the coolant can enter the oil via coolant pump seal between the timing cover and engine block...seam to be a problem on compressor engine...not to shore about the m271.860cgi evo engine...is there any other way the coolant can enter the oil...is there a fix to this...
did coolant compression test ... loosing coolant very slow.. no external leak is it head gasket oil cooler or water pump gasket..on engine block. any ideas..thanks...
