Coolant in oil (Oil analysis)

[Makmak]

Had an oil sample taken and they found coolant in oil. I have provided the report. Can someone shed some light as to how the coolant might be getting into the oil and the possible severity of this. This is a 2010 Volvo 780 with a CM871 with a second motor with roughly 600K. It is a truck I have been looking to purchase, Well, before the sample was taken of course.[/size][/php]

Thanks for any help given
