purged it angled it bubbled it put the heater as well......last few oil changes didnt notice any milky oil so i kno thers no coolant in the oil

did a pressure test several times and the gauge goes down but i still cant find any leaks anwhere. i was wondering if the heater core is clogged or had a leak would it drain out through the ac drain or build up inside ??? (my carpets arent wet on either side)
