Subject: Re: Blown 4.5 head gasket and bubbles in the water.
Hi Bob,
On the 4.5 litre engine the head / block face is "Dry" this means that there are no waterways within the head sealing faces, water only passes to the head via the aluminium transfer poorts on the exhaust side so bubbling must have been caused by something else.
Simply clean up, check the deck and head are flat, and if so, fit a new gasket and test.
Probably all you need.
Do an oil change at the same time though as you will probably get some crap into the oiul return holes so always best to be safe.
Regards,
Julian
