I think whoever owned the car before March 2010 had a lucky escape
I picked up the car today from the garage, and its also had a new handbrake cable and injector return pipes.
The temp gauge now reads 80 instead of just below 70 so new thermo did the job, new brake pads and discs on the front too (although brakes still squeal

)
Yet to see if the rocker cover gasket has stopped the oil leak, I will have to check in the day light tomorrow.
The n/s/f brake caliper has been replaced (expensive!)
Fresh antifreeze
