To give you a better break down...The coolant leaks into the crankcase when just sitting as well as running. I can drain the oil out completely and leave the drain bolt out and fill the radiator up all the way and within 30 seconds to a minute you will start to see coolant draining out of the oil drain hole. I have replaced the waterpump assembly. Tested again and still leaks. I figured the head gasket was bad even though there wasn't any signs of burning coolant nor visually or smell. I went ahead and decided to tear down the top end and inspected the head gasket as well as base gasket. Head gasket looked decent but couldn't find any cracks in head or any warping. Replaced head gasket and base, filled radiator back up and started leaking out of drain hole again. I also took my Snap On borescope camera and looked into the cylinder just to be sure, but no coolant leaking in there. I feel like there must be a hairline crack in the head of cylinder somewhere to cause it to leak as fast as it does into the crankcase but i couldn't find anything.
