Did he cure the fault, as TYRZ pointed out, what was the initial fault? Was the head warped, was it checked??

If the HG was only done 3 weeks ago I'd be straight back to the garage that did it for their input.

Hi thanks to tyrz, ourcar, and smc for replies i have taken it back to the mechanic and he has confirmed its the thermostat that was at fault , seized up, the reason he didn't change it was because he was trying to save me money, ???
nice thought obvoiusly didn,t think to check with me 1st but he is redoing the HG and the renewing therm too at no charge for labour and HG only charging the price of the therm, he has to flush the whole system now as its solid ! so if one thing all the nuts and bolts are all easy to undo as they were undone recently.
once again thanks.:cool:

Good grief, thats a mistake an apprentice would make, not a skilled mechanic, save money my ****, a few quid extra? At least he admitted it.

Anyway, glad its getting sorted M8.

Would a blocked/shut thermostat cause the water system to over pressurise? The thermostat is shut when the engine is cold but you wouldn't expect it to over pressurise. It would cause the engine to over heat and the over heating may cause the over pressuisation and head gasket failure but the temp gauge would have been round the clock assuming it was primed up! Major mistake to not check the coolant system when it was first run.

if it stays shut that will cause it to pressuresied under load. if the sysem wasnt bleed up that could cause it ,or even a blocked rad

I think the above comment says it all - that's probably why the head gasket went first time around. After a head gasket blows it is essential the coolant system be properly cleaned. Just hope the heater matrix isn't blocked.
