water loss 1 litre every 20 miles or so! i took it in for the same reason in december, and was told rad had a leak, so new rad, and while i was at it, full service, all oils and fluids changed (except air con), new front pads, freed-off 'hand brake shoes', new HT leads, cam belt, water pump, adjusters, fan belt, one dist cap and rotor (the other was new from previous owner), thermostat, odds and ends, 2,650 quids worth! and now it looks like it is the head/s (which was my original thought) so i shall be having my negotiating skills thoroughly tested on wednesday!
