Many signs can indicate a worn-out engine bearing, and it’s important to be aware of them. If you notice any of these signs, it’s important to take action right away to avoid further damage to your engine.
In this article, we’ll explore some of the most common signs of a worn-out engine bearing and what you can do about it. By being proactive, you can save yourself time and money in the long run.
What Is An Engine Bearing?
An engine bearing is a crucial component in internal combustion engines, supporting and facilitating the movement of rotating or reciprocating parts like the crankshaft and connecting rods. Made of durable materials like steel or bronze, these bearings withstand high temperatures, pressure, and friction during engine operation.
Main bearings support the crankshaft, rod bearings support connecting rods, and camshaft bearings support the camshaft. Engine bearings reduce friction, minimizing wear and heat generation, ensuring efficient engine operation and longevity.
7 Signs of a Worn-out Engine Bearing
Here are seven common signs of a worn out engine bearing:
1. Knocking or Ticking Noise
A knocking or ticking noise in an engine is a clear sign of worn-out engine bearings. Engine bearings are crucial components that support the moving parts of the engine, like the crankshaft.
When these bearings wear out, they create excessive clearance, causing the crankshaft to move erratically. This results in a distinctive knocking or ticking sound as metal parts make contact where they shouldn’t.
If left unaddressed, it can lead to serious engine damage. Regular maintenance and oil changes can help prevent this issue by ensuring proper lubrication of the bearings, extending the engine’s lifespan.
2. Low Oil Pressure
Low oil pressure could be an indicator of worn-out engine bearings. Engine bearings rely on a constant supply of oil for lubrication and cooling. When these bearings wear out, they create excessive gaps, allowing oil to escape more easily.
As a result, the engine experiences a drop in oil pressure. It is problematic because lower oil pressure means insufficient lubrication for the engine’s moving parts, leading to increased friction and heat. The consequence is accelerated wear and tear on the engine components, potentially causing serious damage.
If you notice low oil pressure on your vehicle’s gauge, it’s essential to address the issue promptly by inspecting and replacing worn-out engine bearings to prevent costly engine damage and maintain optimal engine performance.
3. Engine Overheating
Engine overheating may indicate a worn-out engine bearing. The moving components of the engine, such as the crankshaft, are supported by engine bearings. The engine overheats as a result of the increased heat and friction that these worn-out bearings produce.
Increased resistance in the bearings, which results in inadequate lubrication and decreased cooling effectiveness, is the cause of this overheating. As the bearings age, they become unable to maintain the required clearances, leading to metal-on-metal contact that produces heat.
This might cause serious engine damage if it is not fixed. In order to avoid more problems and maintain the engine’s optimum performance and longevity, engine overheating may be a sign that it’s time to inspect and maybe replace the worn-out engine bearings.
4. Increased Oil Consumption
Increased oil consumption may be a sign of deteriorating engine bearings. The crankshaft and connecting rods require support from engine bearings, which also maintain a thin oil film between these moving parts.
As bearings deteriorate over time, there is a tendency for more space to exist between them and the crankshaft. Because of the wider space, more oil can enter the combustion chamber and burn alongside the fuel there.
As a result, you can observe an increase in oil usage. In addition, worn-out bearings may find it difficult to maintain adequate oil pressure, which exacerbates the issue. It becomes important to regularly top off the oil level, and if the problem is left untreated, it may eventually cause serious engine damage.
5. Vibrations or Rumbling
Excess clearance exists between moving parts as a result of engine bearing wear. This space permits the crankshaft to travel more than it should, which causes rumbling and vibrations.
The engine produces these warning indicators as the bearing ages and becomes less capable of supporting the crankshaft’s rotation. The vibrations, which are caused by the crankshaft’s erratically moving, harm the entire engine.
If not fixed, this problem could be expensive and can seriously harm the engine. Therefore, it’s critical to handle rumbling or vibrations as soon as possible because they frequently indicate a worn-out engine bearing, which, if ignored, can cause additional issues and expensive repairs.
6. Metal Shavings In the Oil
The presence of metal shavings in the engine oil could be a clear sign of a failing engine bearing. Bearings play a crucial role in the engine by reducing friction between moving parts. These bearings may become worn down over time as a result of things like inadequate lubrication, excessive temperatures, or frequent use.
Tiny metal particles are produced as the bearings age and eventually end up in the engine oil. These metallic shavings appear as tiny, glinting specks when the oil is examined, representing the damage that has occurred internally.
This occurrence denotes not only the deterioration of engine bearings but also the possibility of additional challenges because these metal shavings can damage other engine components, aggravating mechanical problems and prompting instant bearing replacement to avoid costly and significant damage.
7. Warning Lights on the Dashboard
Warning lights on the dashboard, such as the oil pressure or check engine light, can signal a worn engine bearing. Engine bearings support the crankshaft and allow it to spin smoothly. When they wear out, oil pressure drops, triggering the warning light.
The reduced oil pressure can lead to inadequate lubrication, causing friction and heat and further damaging the bearings. This can result in engine noise, decreased performance, and potential catastrophic engine failure.
If these warning lights illuminate, it’s crucial to address the issue promptly to prevent extensive engine damage and costly repairs. Regular maintenance and oil changes are essential to prolong bearing life and overall engine health.

Essential Tips for Maintaining Engine Bearings
1. Regular Maintenance
Routine maintenance is key to keeping engine bearings in top condition. Follow the manufacturer’s recommended maintenance schedule for oil changes and inspections. Regular oil changes help ensure that the bearings receive proper lubrication and remain free from contaminants that could cause premature wear.
2. Opt for High-Quality Lubricants
Using high-quality engine oil that meets the manufacturer’s specifications is essential. Quality lubricants reduce friction and protect engine bearings from excessive wear. It’s worth investing in premium lubricants to safeguard the longevity of your engine.
3. Monitor Oil Levels
Keep an eye on oil levels regularly and top up as needed to maintain proper lubrication. Low oil levels can lead to insufficient lubrication of the bearings, resulting in accelerated wear and potential damage. Ensure that the oil level remains within the recommended range at all times.
4. Maintain the Cooling System
A properly functioning cooling system is vital for preventing overheating, which can degrade the quality of the oil and compromise engine bearings. Regularly check and maintain the cooling system to ensure optimal engine temperature and performance.
5. Avoid Overloading
Avoid overloading the engine or subjecting it to excessive loads, as this can strain the bearings and lead to premature failure. Be mindful of the engine’s capacity and operate it within the recommended limits to prevent undue stress on the bearings.
6. Allow for Proper Warm-Up
Allow the engine to warm up adequately before subjecting it to heavy loads or high speeds, especially during cold starts. Cold starts can increase friction and wear on the bearings. A brief warm-up period allows the oil to circulate and lubricate the bearings effectively.
7. Address Vibrations and Misalignments
Address any vibrations or misalignments in the engine promptly. Vibrations can put additional stress on the bearings, leading to accelerated wear and potential damage. Regular inspections can help detect and resolve issues before they escalate.
8. Perform Regular Inspections
Periodically inspect the engine bearings for signs of wear, damage, or excessive clearance. Pay attention to unusual noises, vibrations, or changes in performance, as these could indicate bearing problems. Promptly replace worn or damaged bearings to prevent further issues and extend engine life.
