Do you have some better photos as to where that is located, looks like rubber wrapped around a pipe and held tight but metal wire.


BTW what year is your car?

The area shown is the crank breather tube that goes from the crank case to the inlet manifold. It's not unusual to have a bit of oil weeping from this seal but there shouldn't be any water going through it. Assuming you've mistaken oil for water then fit a new rubber O ring. All will become clear when you remove the pipe!

whip off the inlet and have a good look around, suspects its got some excess oil residue in it.

Is the water being sucked into the throttle body from the more than useless TB heater block, ( rotted out ) then out of the manifold via the crank case breather tube - I'd expect the oil to show signs of water content though.

Just a long shot!

Part 11.
10 litres is about the capacity of the whole cooling system, implying it was totally empty!

Keep an eye on the little pipe at the back of the block to the valve, mine leaked gallons before I found it when taking the head of after brewing up.
