The KV6 isn't intrinsically susceptible to head gasket failure so, unless your engine has been abused at some time in its life or been subject to careless maintenance, neither am I. You'd be very unlucky to have suffered an oil cooler breakage at this time.
I would drive the car regularly and see if it disappears or gets worse.

Regarding the flushing method, I'll be using this guide: KV6 flushing

T-Cut, I disapprove of the author's suggestion that you allow coolant to drain whilst the engine is running.
MGJohn's method of driving the car with a flushing agent in the coolant then draining and refilling is much safer.
Also note that the author isn't using a Rover 75. He mentions a bleeding plug in the top hose which the 75 doesn't have.
