Oil in coolant

Post by Sethsquatch »

Have been driving my pinzgauer 718 p90 incrementally, working out bugs and such, and recently tried taking it on a trip.
45 mins into the trip, temp climbed and touched the red, I pulled over immediately and as I did, a hose burst, leaking what should have been coolant everywhere, but instead started with what seemed like a couple quarts of oil.
The oil cooler is/was brand new, the radiator is upgraded aluminum unit, it has a new turbo, new head gasket as well.
My question is, is there another place somewhere in the engine or cooling system where oil could mix with coolant? All research I have done points to the oil cooler, but seems iffy since it's brand new.
Any input is appreciated, thank you!

Oil cooler failure would have been my first guess. . Next would bee the head/head gasket
Just for reference, which hose burst and does your truck have the coolant afterrun pump ?
Is there coolant in the sump?
