I discover a clicking noise on Alfa Romeo 156 from my engine
Examine your high engine
If you discover a clicking noise on Alfa Romeo 156, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two parts can be the causes of these ticking noises on Alfa Romeo 156. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will hear these clicking noises, often when cold and vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Examine your low engine
If you have distinguished the zone of source of the Alfa Romeo 156 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very complicated and most mechanics will encourage you to replace the engine of your Alfa Romeo 156.
Combustion problem
Finally, if you have the feeling that this clicking noise on Alfa Romeo 156 is connected to the combustion of your engine, there are three possible triggers of it. Examine the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable that your timing belt is shifted and that it does not properly manage the timing of the various engine components to promote good combustion. And finally, the most classic trigger, comes from your injection, which is either blocked or one or more injectors are injured.

I discover a clicking noise on Alfa Romeo 156 in my direction
Examine the condition of the gimbals
One of the most basic causes of a clicking noises in the direction of your Alfa Romeo 156 is linked with the direction of the car. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be replaced rapidly, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Examine the rest of your direction
Finally, when you recognise a clicking noise on your Alfa Romeo 156, it is conceivable that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the case, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I discover a clicking noise on Alfa Romeo 156 coming from my suspensions
Examine the suspension
If you experience a clicking noise on your Alfa Romeo 156 when you pass a speed bump, it is highly conceivable that your suspension block is the induce of the noise. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function and during small jolts that compress the suspensions. To verify if this is the problem that worries you, take a dented road and, at low speed, listen to the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them soon as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Alfa Romeo 156 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a cause. To verify the shape of the spring, position the car on a flat surface and measure that the heights from the ground to the bottom of the body are equivalent on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it means that most likely your springs are worn, if you observe a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, ensure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Alfa Romeo 156 than a clicking noise, don’t hesitate to consult this article.
