Steve,
The problem is to get all the air out of the engine and rad as well. I have a
tail dragger so the rad is high at front while stationery on tail wheel.
So I have a bleed line from the front of the rad ( highest point) then picks
up a bleed point on top of the motor ( Looking from the front it is on the
right side on top of the iron plate) then to a small header tank which is fitted
with the rad cap. From this tank another hose goes from the Rad pressure
cap to an overflow tank of approx a litre. The over flow tank is only ever
filled to 1/3 while the header tank is always full. The header tank is also
fitted with a main line to the water pump housing for water to fill into the
engine, while the bleed line vents air. If you have water in
the oil it will soon become milky. To test for leaks get a radiator
pressure tester which will soon show if you have any problem there. You
have hopefully only picked up condensation in the sump. Sounds good
Neil.

Thanks
Charlie.
That makes sense to me.
Didn’t understand the part of your sentence: “…..and the radiator 'overflow
vent' is open to the top tank of the radiator, instead of being above a pressure
cap seal.”
Appreciate the comments.

In
this case, and in Len's drawing, the swirl tank/reservoir is at cooling system
pressure (pressure cap is on the swirl tank) and the radiator 'overflow vent'
is open to the top tank of the radiator, instead of being above a pressure cap
seal.
