Many thanks Arthur. I will try and give the channels a clean. I dont have the engine our - so I might leave the plugs for now. I am doing a full chassis up restorartion of a S2a once that is done I will do the same on the S1. I am just trying to get the S1 in running condition at the moment.
Is the fat O ring specific to the LR S1 or would repco or another parts shop be able to supply one? Many thanks Scott
As for the colour of the water pump, paint will stop the rust, but if you want to keep the metal look, use some clear lacquer.
