[ROVERNET - UK] Vapor lock/water cooling

Hello Denis,

It has a different purpose.  It allows air trapped at the top of the water
jacket in the inlet manifold to escape into the top of the radiator.  A
consequence of this is that a small amount of water constantly flows through
the hose back to the radiator.  The blockage caused by corrosion deposits
can eventually block the hole and so air can become trapped.

(sorry for my english)
Can you give your advice on my question?
You can see on  pics of V8 engines
a hose between front radiator and the cente of the inlet manifold.
I had cleaned the inside of this pipe on my car: you have one enter,without
outflow and no communication .(usualy full of chalky mud)
Is the function of this space the same of the separate expansion chamber (
used on SD1 V8 ).
Another question : is it better to fit a separate expansion chamber?

    merci pour vos réponses
    félicitations pour cette t belle restoration, Lance
