after doin a head gasket can you blow it again..

Did the gasket then took it for a run.. give it a boot a little and felt fine..
there is so much pressure in the coolant system and its not an air lock...or thermostat.

could it be a water pump(this spins fine and makes no noise)

no gunk or smoke eiher.. only thing missing is the one way valve from the cam cover to throttle body??

1-25nm
2-60"
3-60"
4=60"

this is the method i used instead of 90,90,90 as was told vauxhall changed the torque settings..

cause there is pressure in the coolant system(loads) took it all apart again and decided to do the headbolt up another 60" as they didnt seem that tight..
put all back together NOT STARTIN.. dizzy end not turning?
took cam cover off.. SNAPED CAMSHAFT...wot would cause this?? think valves are ok...hopin

valve timing being wildly out?ie pulleys lined up wrong then headbolts tightened pushed the open valves up against the tdc pistons in turn resulting in the cam being forced up and to break as it had nowhere to go.

havent explained that well but do you see what im saying?
