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.

What is causing a ticking noise in a 1988 Toyota Camry and what needs to be done to fix it?

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.

Why is there a ticking noise on a range rover 1994?

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?

Engine temp is low 140 degrees and a ticking noise is coming from the upper part of the engine What is wrong?

"Engine temp is low 140 degrees" Bad Thermostat (stuck
open) "a ticking noise is coming from the upper part of the
engine" Lifters Make a ticking noise, To stop that there are
these bags that fill with oil. If you run low on oil the bags don't
inflate at you get a clicking. Check you oil level!!! The bags
could be bad, the oil supply could be clogged, or something else
could be wrong.
