hi guys i am having the same issues with my 4.5L GU the mech today said he has found nothing wrong replacing the thermostat rebuilding the water pump, he has ordered new temp sensors and is redoing the clutch fan even though he said it's working at about 80-90%, i have all the same symptoms loss of power, intermittent overheating but just a bit more frequently, and i have a small amount of bubbles in the coolant but no loss of water. will be good to see the results after you have the head done. please update.

PJharps I'd say you've done the head. the coolant shouldn't cavitate to cause bubbles, thermostsat needs to be OE
Might want to post an intro if you haven't already just procedure

has anyone taken off the exhaust manifold and have a look in there see if theres any white or tried listening to the exhaust,is there any popping or is it all smooth idling. it all adds up to head to me

all new items fitted, and no over heating yet. the engine seems to sound better as well.

zerolux hows the car going with the head reco'ed?

Definitely a blown head gasket. Not at all an odd occurrence. With this you will not find water in the oil, nor water consumption, and most of the time, not even compression leakage. If done correctly, it will be fine after you are done with the reco and new head gasket.
Since we are talking about this, be specially careful with the heater hoses, if they go, you will loose watter so fast that the temperature will go sky high way before you even notice, which will definetly end up on a bent head. Yeah, it happened to me :(
Good luck with your fix mate
