Well this is going really well.
Fitted new cambelt, cam cover gasket and thermostat.
CP4L sent me the wrong cambelt kit (the type with a 10mm hole, whereas mine is 8mm)
They sent me the wrong alternator belt (too short)
Alt/PS crank pulley is wobbly so that needs to be replaced, that explains my intermittent power steering
Fan doesn't come on (it's stiff to turn so I imagine it's the fan assy)
Car is still idling high, I ran it up to temperature after putting it back together, I now know the new thermostat is working because my radiator has sprung a serious leak!!!
Fun fun fun, all round...
