No it's parked up with battery off

Waiting investigation

As soon as temp light came on i switched it off

Get my compression tester out next week

[zirk]

So what caused the temp light to come on then?

[woolley11]

Well what I meant was didn't running the engine once the warning light came on 😉

Done compression test today on the MV6. 

All N/S bank of 3 giving 10/12 bar which is good

The O/S bank - no 1 cylinder ? (nearest the front) only giving 7 bar with nos 2 and 3 cylinders giving around 10 bar.

Also all spark plugs on O/S bank are sat in and covered in oil.

Emulsification of the oil too. The car has been used quite a bit prior to going poorly so can't put it down to its lack of use.

O/S Head gasket then as feared - but will replace cambelt, thermostat and transfer pipe while "in" there.

Job for new year anyway - no time before Christmas unless I get someone to do it for me but in East Yorkshire and not sure of any Vauxhall specialists in near vicinity.

Would it be sensible to replace N/S head gasket while car in bits or leave well alone and the assumption if ain't broke....

Seriously?
considering the amount of dismantling necessary to change V6 head gaskets, what possible reason would you have to change just one? When I did mine, the driver's side gasket was rotten and leaking into the combustion chamber(no, I'd not seen that before either). The passenger side wasn't leaking, but it was in very poor condition.
