Default coolant leaking from back of motor..

i have a 98 camaro ss, 105,xxx miles. earlier tonight, after i was done driving it around somewhat hard with a bunch of my other buddies, it started smoking from the motor. its definitely coolant, and i heard it dripping onto exhaust but i couldnt tell exactly where. there was a small bit of coolant on the ground near the back of the motor and im really hoping its a return line or something and not a cracked block. what do you guys think??

Maybe a heater hose or steam vent pipe leaking. Dont rule out a bad head gasket though. Check your oil and see the color

i checked the oil and it was fine, so probably not a head gasket

check the coolant lines where they bolt to the rear of the heads.

Put car on jack stands. Start it up and crawl under there and find that leak.

My guess would be a block off tube gasket or freeze plug in the head rotted out.

Good luck, should be a simple fix.
