Its possible that this ticking sound is caused from driving fast for prolong periods. Its possible that its not the engine that is making the sound, but the exhaust system somewhere. I hear a ticking sound if I drive over 140KMh for long periods. It always stops once the car cools. I hopes this helps.
A ticking or clicking sound is probably lifter noise, the valves need adjusting
That is possible.
Sometimes a ticking sound is a valve lifter. The faster you go the faster the ticking will be. Make sure first it is not something stuck in a tire or something on the fan belt.
You have an old car or it's about to be broken.
that's just the sound of the steel bits cooling down
that probably means its time to get a new car
The most likely cause of a ticking sound in a motor is a bad timing belt. A valve out of time can also cause a ticking sound.
The tinking sound if it is a light sound is probably the fuel injectors working which is normal but I would check the oil level and make sure it is full first it could be lifters ticking or clattering.
the ticking is the blinkers
Diff whine
Could be a bomb but cant be sure without looking at it
