I have a 1997 Camaro Z28 LT1 in Kentucky

about a week ago while driving down the interstate my temp gauge and lights went nuts cause i had a heater hose bust at the heater core flow valve just off the water pump. as soon as the lights went on I pulled over and cut the car off with the temp wrapping around the 260 mark. on the side of the interstate i rigged up a copper couple that happened to be in the hatch from that was going to be used for the TB bypass. fixed refilled coolant and been running normal temps. The last few days i've began to notice a tiny bit of power loss once it warms up. Then once i got home this morning i seen white smoke or steam coming from next to the valve covers near the intake manifold. so when it cooled off and i woke up this afternoon i checked the oil and no coolant and then popped off the radiator cap and started her up and topped it off cause it was low. after about 30 seconds i started to get a continuous amount of bubbles in the radiator. My question is " Blown head gasket?"

 

More than likely yes. To get a definitive answer use a combustion leak tester. They can usually be rented at NAPA and the like. It measure CO2 in the antifreeze.

 

park you car on a hill (steep as you can find) with the front on the up side, fill the radiator and blead the air out of the cooling system. drive it around the block let cool and do it again. and again. if during this time you continue to get bubbles then i would say yep you got something goin on. cracked head, block or blown gasket.
