For your car to work efficiently, every component of the combustion engine has to work in perfect synchrony, and timing belts and timing chains contribute to that precise harmony. They are components that attach to the crankshaft and the camshaft and allow for timely revolutions between them. This in turn results in pistons working the opening and closing of the valves.
In terms of durability, timing chains are better than belts. This is because timing belts are mainly rubber, which undergo a natural deterioration process after five to ten years. Also, rubber-timing belts also have a mileage life of about 80 thousand or more.
When you take all of this into account, along with the effects of heat and mechanical stress on rubber timing belts, then encountering rubber belt issues becomes a possible scenario. Many people are unaware of the indications that scream timing belt replacements. Below are signs that indicate that your engine’s timing belt has surpassed its lifespan.
Timing Belt and Ticking Noise
When the timing belt exceeds its time interval, it becomes responsible for a ticking sound inside the engine. This ticking noise is however more common in cars that have timing chains instead of timing belts. When a timing chain wears, it tends to extend in size over a certain period, and when it does that, the metallic pieces scrape against the exterior parts of the engine. This results in a ticking sound from the engine.
A worn-out belt loses its dexterity and strength that helps it attach firmly to the cram shaft and camshaft. Once it begins to wear, it can sometimes slip on the cram shaft and disrupt the timing of the revolutions. This slip of the cylinder means that the car will misfire, and not respond to stepping on the throttle with the same acceleration. If it gets worse, then it may result in a misfire situation that can turn into catastrophic engine damage.
Oil Leakage from the Engine
Another indication that points to a belt issue is oil leakage from the front end of your engine. Car manufacturers screw the timing belt cover tightly to keep the belt secure. Therefore, an oil leak is not something you should be expecting from that region, and when you do notice it, it can point to a worn-out timing belt, bad gasket, or even something worse.
It is very difficult to tell whether it is the timing belt that is at fault or something other than that. This is why you should be looking to replace a timing belt once it has passed its mileage or age, regardless of the signs or indications.
