Subject: Re: Blown 4.5 head gasket and bubbles in the water.
An update on my own situation.
Fortunately I don't have any significant problem but it's worth sharing. The only problem I appear to have had has been that the radiator cap wasn't effecting a seal. What I experienced was frothing water/anti-freeze splurting out of the cap and being thrown onto my windscreen. I was concerned about what was causing it to froth up and suspected water pump cavitation caused by a restriction on the suction line from the radiator or air being sucked in somewhere. No such problem could be found. Several experiments mixing up anti-freeze and water in buckets with a food blender showed that they will froth up through normal mixing. Sorting out the radiator cap alone appears to have solved this problem. I did 150 miles at about 60-65mph on Saturday and neither the car or I suffered any ill-effects.

Adam,
Could you post a photo of your damaged gasket?
Have you discovered the cause of the air/gases getting into your water? I've just developed similar problems. Yet to start stripping down and doing a compression test although no power loss.
