Yep. 8 is at the back, right hand side as you look at the motor from the front. That one gets the screen-washer jet/rainwater leakage sometimes. I guess yours is on the front end of the motor on the same side, nearest to the radiator hose > thermostat entry? If so that is or has been a leak and need investigating. If you have a crystalline deposit you had/have coolant there. Coolant may be sitting still inside the rubber tube around the spring plug contact and needs cleaning up anyway. Get some dialectric grease then, not that that will actually cure any leak if there is one of course!
