No trace of coolant in the oil, nothing leaking anywhere. You can fill the tank with antifreeze to the cold mark and 2 days later it is bone dry. Truck runs fine temperature is great, heater core not leaking, where is it going?

Hi i have a 1998 Chevy 1500 4.3 V6 its got 127xxx miles it recently started having the same symptoms as listed above (resevoir drains, No visible leaks, oil looks good ON DIPSTICK etc.) except now when i start it up from cold (around 30-40 degrees outside temp) it makes a low pitched "ticking" sound under the hood my friend said its lifter noise and not to worry about as it doesnt puff out white smoke anywhere but i need too get it figured out before the snow flies in about 2 weeks. Thanks!!
