I have a 140 GT TDI BKD engine that is using water with no leaks (to my knowledge)
I know the early engines had problems with porous heads, and do tend to use a little, it seems i am topping up every couple of days, particularly after motorway driving.
Is there a cure for this issue ?
or Can i get the head from a later model that did not have this issue and change it over.
Help and advice most very welcome, particularly if anyone has done this
