if its evaporating as fast as it leaks g0rsq your looking for something that is no longer there... and if it only does it when the engine is hot... you have a double whammy to contend with.
since it might only happen under particular circumstances, and you dont know what they are... it happens.. but you dont know when or how...
asking someone if they know what lottery numbers will win today.. is close to any answer... pointers are all you will get..
if you dont know where its leaking from... then how can anyone be certain whats causing it?
OMG - doom and gloom - how negative can we be..............
Tom was asking for help, g0rsq, gave Tom a pointer, strangely enough as I read the symptoms, I too, was thinking water pump, but maybe Tom should just scrap the car.
