Oil in the coolant tank indicates a head gasket leak.
Vehicle likely overheated, or for some other reason, the head gasket has been breached, allowing coolant to be burned in the engine. The coolant is consumed, appearing as whitish smoke emitting from the tailpipe.

An oil coolant?æ hose is a tube or pipe that allows engine oil to circulate via the radiator in order to cool down. Without an oil coolant hose, oil will get to hot to operate efficiently.
Engine? 3.1L V6 are notorious for intake manifold gasket leaks. get it fixed soon or your engine is at risk. My Lumina had oil in coolant and coolant in oil. If there is tan foamy stuff on oil fill cap, coolant is in oil too.
The coolant has oil in it. Possible causes are a failed headgasket, or a leaking oil cooler,
