     -Why doesn't everybody just put on a secondary and cheaply bought, 
     simple, closed-cooling system recovery tank?
     
     I bought a pink BUDWEISER water bottle that matches my car's colour &
     fits perfectly between the header tank and radiator frame. (Thanks 
     Ramon).
     
     Works for me...I have no air in my system(no, not my digestive tract) 
     and my header tank is completely full of coolant.
     
     Sounds like a "swirl pot" might be better for mixing a really good 
     Martini or Margarita!!

 I've just given DG Motorsports a ring and got the low-down on the
swirl pots: 
     
 A swirl pot is a metal pot about the size and shape of a Cocoa
Tin, with a pipe leading into the base, and then another leading out 
through the top. The cooling water enters at the base, and swirls up the 
sides of the pot (imagine it taking a path resembling a coil spring), and 
exits at the top. There's also an air pipe leading out through the top, 
that vents up near the top of the radiator. 
     
 The theory behind the system is that V8s don't like air bubbles in
the coolant, and when the water passes through this pot and swirls around, 
the bubbles escape and are forced out the vent pipe, whilst the water 
remains within the system. Since the coolant now lacks air bubbles, it 
operates much more efficiently, and prevents the engine from overheating. 
     
 This system works on a racing Griffith - a car that possibly has
more heat problems than the average Tiger, and it should be transferrable. 
     
 So Roland, it's not to do with Pigs after all... Sorry!
