Did you pour anti-freeze in the oil tank, or vice-versa? The reason ask, is there is no oil tank, the oil fill is directly into the engine. There is a coolant reservoir. If you poured oil in the reservoir, it will stay on top, until it is allowed to get hot and eventually becomes emulsified and distributed in the cooling system. If that happens it will soften and deteriorate rubber.

If there is coolant added to the oil, it can be drained. In contrast, the coolant will rest on the bottom of the oil pan and be the first to flow when the plug is removed. If it has been run, you may want to have the oil changed. The crankcase has the ability to cook some water out. the oil temperature runs hotter than the boiling point of water, and it is released as steam.
