Thanks Ian,

Thanks! The 2 radiators I have do not have upper or lower ports - the ports are on each on the top of the fairly inclinend radiators. I now changed the direction of the flow of coolant so now the upper port of the swirl header tank is the return line from the radiators. So I am feeding the cooled do...

Thanks, you are correct. I do not want to reverse the coolant flow, but I see no other possibility without major changes in the expansion bottle. I cannot pull coolant from the bottle without air (even when I add the connection in the lower part of the tank) - there is still air above the coolant le...

It is said to be a 4.5 Rover engine, dry sump, Carillo rods, big valve heads, Cosworth forged pistons. Ther...
