help

I have a 94ls. Lately it has been overheating a little. I noticed it does it more when I have the a/c on. I've noticed the smell of antifreeze but can't find any leaks. I put the car on my friend's lift, but still didn't see anything. I had the water pump, thermostat and water hoses changed about 3 months ago. I also noticed the car has been running low on oil. I've needed to add at least a quart every 5-6 days. I just don't know where its going. Maybe its time for a rebuild, but don't wanna cuz money is so tight. If anyone has any ideas as to what is going on with my car, please let me know. BTW, the only mods I have on the car is AEM short ram intake, Tsudo 4-1 header,and Tsudo fireball exhaust. I also have Tokico coilovers but those don't have anything to do with my engine or cooling system.

Anybody have any ideas?

Sounds like it could be a bad head gasket. IF you start the car and the exhaust smells like antifreeze then that is most likely your problem.
