Negligence can be the root of many unwanted expenses. Whether it’s the maintenance of an industrial vehicle or a conventional car, issues not fixed on time can turn out to be bigger expenses. The same rule applies to automobiles. Minor problems can turn into significant ones if fixation is delayed. The repair may cost higher depending on the component. For instance, if a major engine component is damaged, it can lead to complete engine failure.<\/p>\n\n\n\n

One such major component is the engine valve, which like other parts is prone to damage. We will go through the possible causes of engine valve damage and some effective steps to take in this regard.<\/p>\n\n\n\n

Engine Valves Function<\/strong><\/h2>\n\n\n\n

Engine valves are prone to damage and can cause serious engine issues if not maintained properly<\/figcaption><\/figure>\n\n\n\n

The engine valves<\/a> control the airflow inside a vehicle\u2019s engine. These valves are responsible for allowing air or liquid flow during the combustion process. As a component performing such a vital function, any damage to it can be hazardous for the engine.<\/p>\n\n\n\n

Engine valves, like other components, go through a natural process of wear and tear. The engine components need to be built with maximum precision as the slightest misalignment can lead to failures. Some of the other problems caused by engine valve damage include valvetrain noise, increased fuel consumption, a compression leak or a complete valve failure.<\/p>\n\n\n\n

Symptoms of Valve Damage<\/strong><\/h2>\n\n\n\n

Just as you would take immediate action against symptoms of car engine failure<\/a>, valve damage also requires a prompt response. Modern vehicles come equipped with camshaft engines that diminish the chances of valve damage; however, the majority of older models may encounter valve problems.<\/p>\n\n\n\n

Therefore, it is important to know the engine valve problem symptoms to take immediate action if your vehicle shows any such signs. Listed below are some common symptoms of engine valve damage that you should be aware of:<\/p>\n\n\n\n

TICKING NOISES FROM THE ENGINE<\/strong><\/h3>\n\n\n\n

If you hear ticking noises from the engine, it may be because of damaged engine valves <\/figcaption><\/figure>\n\n\n\n

If you come across popping or ticking noises from the engine<\/a>, there may be some engine valve problems. The ticking sounds tend to get louder as you accelerate. This may be because valves have worn off or a possible misalignment. Either way, lubrication in the engine may be affected – leading to the ticking noises.<\/p>\n\n\n\n

ENGINE POWER LOSS<\/strong><\/h3>\n\n\n\n

Another symptom of valve damage is low engine power<\/a> and performance. Valves are designed to fit perfectly without no or minimal leeway. However, in case of oil leakage, a gap might be formed – causing the valve to lose its seat.<\/p>\n\n\n\n

Additionally, burnt valves can also contribute to a decrease in engine performance and power loss.<\/p>\n\n\n\n

BLUE SMOKE COMING FROM THE TAILPIPE<\/strong><\/h3>\n\n\n\n

If you see blue smoke from the tailpipe, your vehicle may have an engine issue. Although blue smoke indicates several problems, engine valves may be a certain one.<\/p>\n\n\n\n

Damaged engine valve seals and guides make room for oil to get to the combustion chamber. This results in oil burning along with the fuel. Drivers are also more likely to experience oil levels dropping rapidly.<\/p>\n\n\n\n

Engine Valve Damage and Causes<\/strong><\/h2>\n\n\n\n

Whether your vehicle is equipped with V-engines<\/a>, W-engines or any other type, valves need to be in perfect condition for an effective run. However, engine valves can wear with time or may go bad due to bad driving habits. That said, let\u2019s go through some common types of engine valve damage and their causes.<\/p>\n\n\n\n

IMPROPER INSTALLATION OF VALVE SPRINGS<\/strong><\/h3>\n\n\n\n

This happens when the spring isn\u2019t fitted properly during installation. The improper installation of the spring can cause a lateral bending movement on the valve\u2019s stem. This can lead to the complete wreckage of the valve guide.<\/p>\n\n\n\n

IMPROPER INSTALLATION OF HYDRAULIC TAPPETS<\/strong><\/h3>\n\n\n\n

If any of the component is not installed properly, it may cause damage to the engine<\/figcaption><\/figure>\n\n\n\n

There is a minimum time frame of 30 minutes after the installation of the tappets. This problem arises when this period is not served. The oil inside the tappets doesn\u2019t get enough time to escape the area. This results in the valve\u2019s collision against the piston which may result in bend and break.<\/p>\n\n\n\n

IMPROPER VALVE CLEARANCE SETTINGS<\/strong><\/h3>\n\n\n\n

This issue usually occurs when the valve clearance is set tighter than it should be or when the maintenance periods have been exceeded. This can lead to overheated valves and burns in the valve seat area.<\/p>\n\n\n\n

MISALIGNMENT AT THE VALVE GUIDE OR THE VALVE SEAT INSERT<\/strong><\/h3>\n\n\n\n

Any misalignment in valve guide or valve seat may cause burns in the valve seat area<\/figcaption><\/figure>\n\n\n\n

When the valve seat or valve guide alignment is non-centric, misalignment is likely to occur. When this happens, the valve cannot close properly. This may lead to burns and damage in the valve seat area.<\/p>\n\n\n\n

EXCESS VALVE GUIDE CLEARANCE<\/strong><\/h3>\n\n\n\n

This engine valve damage occurs when the valve guide clearance is too big. This usually happens due to excess wear of valve guides. <\/p>\n\n\n\n

INSTALLATION OF WORN PARTS<\/strong><\/h3>\n\n\n\n

Old or used spare parts can cause damage to the vehicle. Therefore, it is essential to choose spare parts wisely<\/a> for better results. Using worn-out parts can also cause engine valve damage in several ways. Pay extra attention when installing the following parts:<\/p>\n\n\n\n
