I had it a few years ago when on track a couple of times, where the expansion tank filled and overflowed, bubbling in bottle as well.

I've always assumed its an early sign of HGF but I've changed the radiator, hoses and coolant since then and it was fine on the last trackday i did - although it was in February so the ambient temp was much lower.
