So first up a big thank you to all who helped get me this far! On Wednesday we got Kizbee fired up for the first time in over 8 years and after a trundle through the village celebrated with a couple of ales. Too soon. Today the heat coming off at idle was huge and after another 5 minute trundle oil smoke was billowing; from the breather chamber and filler neck when inspected. A digital thermometer in the dipstick showed 80°C. The oil pump was relatively new so I didn't inspect on the rebuild (doh) neither the cooler (though I wouldn't know where to start) I'm thinking it has to be these 2 as possible culprits. Before I strip the fan out to get to them had anyone any other suggestions? Cheers folks.
