Had a spare few hours last night so I spent them wisely...................

I had to blank the top of the thermostat housing off so that the water return came from the swirl pot only..........................



Then i hooked up the swirl pot..................



There were some surface rust showing on the rocker cover..........



I stripped the rocker cover off to have a better chance of cleaning it......







I used WD40 and some wire wool but could get it off, so it will have to be sent away to be treated and re-chromed
