I have a vx and it seems to be going through a lot of water.
It runs on gas and the oil is still clear after 8K and there is no white stuff under the filler cap so its not a head or a head gasket.
Any ideas.
do a presssure test and check all the hose fittings? Check the resevior to check there is no leaks... Check the radiator for leaks...
if its not leaking it externally then my guess is inlet manifold gaskit
check the vapour line for signs of water entering the engine thru the gas system
check that the Actual mixer isnt leaking,

check your heater tap, and your radiator tanks for cracks around the brackets that hold the fan setup , use a torch and look for stains
thanks I will have anothe look its gotta be going somewhere
Have a look under the bonnet at your heater tap . They get brittle with age , happened to mine it was using heaps of water and i grabbed the heater tap and gave it a gentle pull and it snapped off .
there are three types of people in the world , those who can count and those who can't
also check water pump, mine went, started losing small amounts , it would just vaporise, then it finally went, and then u could see the fluid running down front of engine
Had a similar problem, VR V6 on gas, turned out it needed a new radiator cap, even though the one on it looked in good condition.
