coolant leak no visible signs
i have a 93 z28 that is losing coolant even with the engine not running
you can fill the radiator and come back about an hour later and it's empty
i know it can't be the heater core cause all hvac components have been stripped
there are no puddles on the gorund either

but, please clarify something
Engine off and cool
you fill the radiator completely
you do not run the engine
you walk away a few hours, come back and it's down a lot again?
it's important to be precise with descriptions

^ Right, something should show as full sooner or later....either the radiator or crankcase.
Just don't have the car parked on a hill, sure would hate for it to float away!

fill radiator
do not run engine
come back few hours later and it's empty
and i'm sure it's not the recovery tank
however i was told that it could be back flowing through the oil cooler and going straight into the oil pan

Check the dip stick for water. It should be showing over filled as the oil will float on the water. If there is any chance there has been coolant in your oil DO NOT start the car. You will wipe out every bearing in the motor.

I'd just bypass the oil cooler. All you need is some caps from the auto parts store that'll go on the water pump and the drivers side bottom radiator.
Then next time you change your oil filter (which should be right now if you have coolant in your oil), you can remove the cooler piece and install a filter directly on the block. What I don't remember is if you need an adapter or a different oil filter. I haven't done that yet, but I did do the oil cooler bypass caps on my '94 LT1 earlier this year with no trouble, and I live in the desert.
