Re: SER1 Valves

Unfortunatly the landy was not in a running state when I aquired it. 
I considered doing a compression test but the coolant system was so
plugged with scale and silt I thought I should clean it out before
running it at all. The thermostat body was totally full of salts, the
rear cover plate for the thermostat/choke light cover plate was
corroded all the way through the water pump was near frozen from all
the sediment.
however from what I can see the engine looks to be in great shape otherwise..

Thanks,
Ian
