I hate this damn car

So context when i drive this car about 70+ for longer than 15 minutes smoke comes out from this area.Id assume its burning oil from the one of two oil leaks i have but idk.Then it always smells like coolant no matter what.Its the worst cause idk wheres its leaking or burning from since theres never puddles below my car when its parked.THENNN my coolant jug is never empty but my heat works when my rpms are over 2500 so ik something is blocked.So i need to replace that blockage and probably get a new heater core.Back to the original problem at hand though,why does it smoke from this specific spot.(Im also losing my mind with the other repairs i have to do on this car)
