Subject: Re: Blown 4.5 head gasket and bubbles in the water.
Sounds like the moral of the story is, that the 4.5 is a pretty robust engine and we are overly sensitive to the simple things! Glad that all is well. It is worth ensuring that the spring seated overflow valve is clear and don't overfill the header tank. If the water is expanding and cannot get out, the radiator cap is not man enough to contain it. Hence wet windscreen.
