as you know from previous post the big ends of my car went.well the saab garage sent them to an engine works who sorted them and are now in the process of putting the car back together.i was supposed to get the car back today so i phoned them to c what time i was to collect it at and they said the head gasket had to be replaced and they were waiting on the part.
my question is what is a head gasket and more important is it an expensive part.thanks for any help.
