I have a ticking noise coming from under the hood and it seems to get worse when the car is heating up this happens from the time you turn the car on until I turn it off?

Your valves may need adjustment. As an engine ages the parts develop larger than normal spaces between them through wear, what you hear is the valve lifters tapping because they have too much gap between their surfaces. If the engine is fairly low on mileage more frequent oil changes and the use of an oil treatment can often times make the noise go away, the thicker oil forces the parts closer together thereby stopping the noise.

Before I can answer that question, can you describe where the ticking noise is coming from? Front of the vehicle? Rear? Engine? Is it coming from your Wheels? If its coming from the front of the vehicle you might require an oil change. If its coming from the rear of the vehicle it could be your axle. If its coming from your wheels it could be either wheel bearings or a backing plate for your brakes. Does it happen at regular intervals? Are they random and sporadic?

Try to locate the ticking noise. Is it the engine? Is it ticking when you are driving? When you are sitting still? It could be as simple as a stone stuck in yoru tire, everytime it hits the road it ticks. it could be a lifter in the engine. Try to be more specific as to where and when the ticking happens.
