Re: oil leak and overheat.
For one you have UNO HEADER!!! It's an inline 4 and theres only FOUR places for exhaust to come out. Two, putting trays under your tires and spinning is the most stupid thing ever. You don't deserve to drive if you do stupid shit like that.
Now, is your radiator fan kicking on? Do you have coolant? I'm guessing not since "your engine is using it." The motor doesn't use coolant, it circulates throughout your engine to cool it off. Your loosing it somewhere and you need to find it.
Add oil if you have none, if your car smokes then your burning oil. Add that to your oil light comming on and you beating on the car harder than a boy hitting puberty, look forwards to buying a new motor.
