From description, yes oil cooler, but oil in header tank is usually more obvious, has it had oil cooler cover plate re sealed perhaps? Maybe just a bit contaminated? Or early signs of failure.. :-/

Rule is

Oil in water, oil cooler.
Water in oil,(among other symptoms) head gasket.

No point until you change the oilcooler.

And using it before you do risks nackering pipes, seriously blocking the rad etc
