ford ranger losing water

[wallis1007]

My mate has a ford ranger with a mazda diesel engine (only a few years old). It has started blowing water out of the exhaust recently to the extent that he is topping the rad up daily with approx a pint at a time.The car went in to the garage today for pressure test as the head gasket was suspected, and the results show no pressure loss anywhere. There are no obvious external water leaks.Any suggestions how the water could be finding it's way to the exhaust? There is no oil/water cross contamination.

well i dont know if this will help but if you took it in for a pressure test and it was fine it might be the cap thats leeking the water. i work for ford and have come across this a few times on the ranger but if it is coming out the exaust alot then you should hear some pinking and it should throw the MIL light on but im affraid that there are lots of possibilitys and with out seeing the hole picture i couldent give you a anser just a guild

sorry if this dosent help
