G12, G12+, G12++ and G13 are all pink / purple.
Is the car outside? Possible some rain got in at some point?

Hi Bret
The coolant colours made me say reddish or brown if a bit old or the system was not clear of corrosion.
When not working on it the bonnet has always been on, we have had one or two heavy rain episodes but no way i can see for how it would get in.

wasn't the rocker cover loose for a while?
If so, then this is water / condensation that has got inside, made grey by the oil.

Yes it was, that would be a lot of condensation - about 3 tablespoons? If that's all people think it might be then I'll stop panicking and go back to the reassembly (fingers crossed).
