Question type: Maintenance & Repair

I have a 2004 Pontiac Grand Prix. I have a oil leak coming somewhere
from the 3.8 engine. (not supercharged), the other day my care over
heated bad and was blowing bad white smoke and blowing black smoke
from the back end, i still kept driving on it until it eventually wouldnt start
anymore. Come to find out so far the radiator split. My dad who is a
mechanic replace the radiator and the thermostat. My car is still over
heating.. I need to find the issue because i still owe on my car and well over
4 grand. my car has 150,000 miles on it. The fans work and i even blast my
heat and have my windows down to help. Itll go from right under the middle
temp line to going above to back down to all the way in the red i need to
find the issue. Also, sometime when turning or driving sounds like water
swishing back and forth once in a blue moon underneath my hood. I am a
single mom and need help on this. Please let me know. We have made
sure and bleed all the air out as well.

water swooshing around means low coolant level. Since you drove it until it wouldn't start anymore, I surprised you got it running again. Did you Dad change the oil as well, since it probably got very hot. So have him perform a cylinder pressure and or leak down test to determine the condition of the engine. You might have a failed headgasket to a cracked head or block.
