ok ive been losing water, and can use as much as 2ltr a week, thought it was the head, but changed the thermosts and rad cap no difference, had my mechanich pressure test again today, he said he had it up to about 3 bar and not a jot came out, he took off timing belt cover and underneath trays to check for staining etc, it did lose a bit of pressue he said but certainly nothing to be alarmed about, i then took it to a garage that uses a dye thay changes colour if combustion/exhaust gasses are present in the water, no sign of anything and they daid it looked spot on, so what the hell could it be!
