cooling system fault? or head gasket failure?

After an interesting day of ups and downs, i have the following situation.
1. I ran the engine without the thermostat. Got it warmed up. But no temperature indication at all- maybe anomalous readings previously? Where are the temp sensors?
2. While running, expansion tank cap off, there is a regular stream of bubbles into the expansion tank. Cap on, the system becomes pressurised very quickly, and the hoses become hard and noticeably balooned. Even though I've made big efforts to ensure no air is trapped in the system.
Head gasket failure?
3. Very moist exhaust- but this may be due to 2 months of sitting unused.
4. Whoever did the timing belt needs shooting. Three of the cover bolts on the right hand belt cover have no hexagon left. So the front of the car has to come apart to get a drill in there to drill the remains out.
5. both fans are running- the viscous fan seems to work ok. Should the electric fan be running constantly?
So, not really a success. And a small pain in the derriere if one or other head gaskets have gone.
Mit freundlichen Grüßen
Marcus
