ok it's only very minor but that is where major problems start.

the leak is from the heater control valve, where the cable goes into piping to move the valve to allow the coolant to pass through the heater core. it only does it under load (above 2k) and is very slow at that but i will get 2-3 drops every 10min. Is this fixable? or do i have to replace the valve and flush the coolant system out?

 

Common 280zx problem & it needs to be replaced. You can get them new from Nissan for $60-$80 US... or source one from a junk yard.

 

beautiful i found a guy about 30miles out of town with about 20zeds in his back yard so i think i'l be paying him a visit again

 

as cheap as they are i would go new. just my .02 cents
