Replaced heater core - Leaking coolant on headers
The heater core on my 1985 z28 burst and my interior got flooded with coolant. I replaced it and there doesn't seem to be a leak coming from inside or from firewall coolant hoses.
However there's still a leak that seems to be hitting the y pipe/headers causing it to smoke up. Very small leak it appears and only happens when I turn the car off.
Any idea as to what this could be? What else usually blows when the heater core goes?

Where is the condensate drain on these cars? ANY fluid build up will come out of that drain. Might be worth checking.
