Hi and thanks for that daz a reassuring word always helps. Never the less I will be checking everything that I mentioned previously as soon as I get a minute away from work . I have noticed it is using a small amout of water, half a pint every 150 miles or so. Ive had the dye test on it or the sniffer as we calk it and its not showing any combustible gas through the water system therefore the head gasket would ok . Any ideas . Cheers
