• Faulty pressure relief valve: when the pressure relief valve not working properly then it causes the oil to
come in excess or not enough oil which is required for lubrication.
2 In Oil filter system
• Clogged Filter: The most common cause is dirt, debris, and contaminants in the oil causing a clogged
filter. This reduces oil flow and may cause engine damage.
• Poor maintenance: Irregular or inadequate maintenance (such as not replacing your oil filter at
recommended intervals) can cause it to become less effective over time.
• Inferior quality filters: Using inferior or counterfeit oil filters can lead to premature failure as they may not
filter oil effectively or have a shorter lifespan.

• Extreme Conditions: Operating in extreme temperatures or harsh environments can accelerate oil filter
wear and lead to failure.
3 In Oil pressure relief valve

• Wear: Over time, valve components can wear out from continuous use, resulting in reduced effectiveness
or failure.
• Corrosion: Contact with corrosive substances or environments can damage valves and cause failure.
• Incorrect pressure settings: If a safety valve is set to incorrect pressure specifications, it may not work
as expected, leading to malfunction.
• Mechanical Damage: Physical damage to a valve such as: B. Impact or excessive force may cause
malfunction or failure.
• Lubrication issues: Insufficient lubrication of valve components can lead to increased friction and wear,
which can lead to failure
4 In Oil pressure gauge

• Extreme Temperatures: Operating at extremely high or low temperatures can affect the accuracy and
reliability of your meter, especially if the meter is not designed for such conditions.
• Component wear: Wear of other components in the lubrication system, such as: B. Pump or pressure
regulator, can indirectly affect the performance of the oil pressure gauge.
• Age and use: Like any mechanical or electronic device, oil pressure gauges will deteriorate with age and
frequent use, eventually leading to failure if not properly maintained or replaced when necessary.
5 In Oil cooler
• Clogging: Accumulation of debris, dirt, or sludge in the oil cooler can restrict oil flow, resulting in less
efficient cooling and possibly causing the lubricant to overheat.
• Corrosion: Exposure to corrosive elements or improper maintenance can cause the oil cooler to corrode,
causing leaks or structural damage that affects its functionality.

• Overheating: Operating the engine or lubrication system at high temperatures for extended periods of time
can put excessive stress on the oil cooler and cause it to fail prematurely.
• Pressure surges: Sudden changes in oil pressure, such as excessive pressure surges or spikes, can
overload the oil cooler and its connections and cause cracks, leaks, or other failures.
• Poor Maintenance: Inadequate maintenance practices, such as: Other issues, such as infrequent cleaning
or failure to replace worn parts, can cause oil cooler failure over time.
