Great to hear she is not sitting in the Barn anymore. Just like Bob said it's the upper hose connection at the the thermostat housing, the thermostat housing to intake gasket or the flat rubber O-ring between the timing cover and intake. If you do not want to buy a pressure tester the major chain parts stores will usually loan one out. Wait till the engine is completely cool and wipe up the whole area really well. Pressurize a little higher then the pressure that is stamped on your radiator cap. Let sit while wiping your finger around the areas we mentioned until you find the leak or leaks. If it ends up being the timing cover to intake seal you need to remove the intake to replace it. Make sure and repost if it is for tips.
