[procta]

I assume you've checked the HG since, sniff test and compression test?

I just can't imagine procta without a Metro.

There has been a time tom, many moons ago, when procta didn't have a metro. If things don't pull through, you will see procta with out a metro for good!

Yeah as above. If compression is fine. Coolant system is not pressurising or losing water and no fumes in the coolant...
Then why do you think its HG?

Rough running when hot sounds like sensor issue

Due to the  fact it still pressurising and running like it is, but it has settled down then pressurised again.  

in the last few post you mention cooling issues still is this air/bleeding issues? just a thought if you have air in the system and it gets too a sensor that goes to the ecu will that give the problems your having?

As stated Vincent, we have ran a hose through the full system to the point it was spotless and the fucker still  pressurised, I took it for a little ride around the block to help circulate the water and then bled it, It worked then it started to act up again.
I know these cars are a right bastard to bleed at the best of times, but its one thing I am not going to rule out that the head gasket repair hasn't been a success.
