Pull the plugs and find out if its inlet manifold gasket, if plug 1 or 4 are nie and shiney then its probably inlet manifold, if not then could be HGF.
It has been losing coolant quite cheerfully (about a pint everytime I check) for quite some time - ie 12 months or so. I got Ali to check last time last month but he couldn't find anything, although it does seem to have got worse since. It nearly overheated a couple of weeks ago, the water had got v low I suspect...
The other things you say about inlet whatnots is errm a bit of mystery to me, the car is living outside at the moment as the garage has been pressed into use as a woodworkingshop but that will end Sundya and I will make a concerted effort to find aforesaid leak...

Sigh. The cooling system won't overheat just because the tank level is low. The tank represents a small fraction of the total coolant volume. It's there to provide somewhere for the coolant to expand when hot, as well as a convenient place to allow the system to be filled. It should sit on the min/cold line when cold and rise to the max/hot line when hot. Any other behaviour (e.g. sits at min when cold and then drops when hot) implies air in the system. If it's actually losing coolant as well you would tend to smell it if it's the radiator or heater matrix.
I'm assuming there are no drips and leaks under the car (Ali would have spotted these, typically), so I'm going to hazard a guess that the coolant is being lost into the engine. This would go hand in hand with potential overheating/running hot.
Good luck.

Hmm. You are making my policy of self delusion very difficult Robin.
I have faith in Ali, but the car has been leaking water for 2-3 YEARS. Two other independents in Scotland failed to spot previous leaks, one of which was the rad. Although the rad was replaced (last summer) the leaks continue (and worsen).
Now obviously this is not necessarily cause and effect, ie I may well be looking at consecutive problems with the same symptoms.
I suspect the water is going into the engine, but the car is used every day, and I am surprised that a water leak into the engine has lasted so long without doing any damage. Having said all that the car is coming into the garage tomorrow to sit on paper so I can see once and for all if the water is coming out the bottom.
