The bearing is the mechanism that is mainly used to reduce friction between the two components. This can be in an industrial machine, a car, a toy, etc. And as a result of reducing friction, wear is also reduced.
In addition to bearings, also known as bearing, sleeve or ball cage. This element is very important and its good condition is necessary for everything to work properly.
It is important that you take care very seriously. engine bearings, as a damaged transmission or a completely broken engine can be the result of engine bearing failure. So, if you find any symptoms that indicate that the bearings are in poor condition, you should have them repaired or replaced as soon as possible.
Because, here we will tell you four symptoms that indicate that your car’s engine bearings already need to be replaced.
1.- Engine noise
A symptom that indicates that there is a fault in the engine bearings It’s engine noise. Connecting rod knock, which is a stabilized hammering that increases linearly with rpm, occurs when excessive clearances as a result of bearing wear cause the large ends of the connecting rod to strike the crankshaft at the bottom and top of the piston stroke. So a knocking rod is definitely a symptom of worn engine bearings.
2.- Loss of oil pressure
Loss of oil pressure is also one of the symptoms of engine bearing failure what you should know Normally, the oil pump flows a fixed amount of fluid and if there are small leaks in your engine, such as leaks in the space between the engine bearings, rocker arm or hydraulic lifter, your engine will lose oil pressure due to oil escaping from the oil channels.
Therefore, gapsas a result of excessive s between the bearings excessive bearing wear will cause loss of oil pressure, especially at low rpm when the pump is running at its lowest speed.
3.- Metal shavings in oil
Metal shavings in engine oil are another symptom of engine bearing failure. Normal bearing wear produces a likely amount of aluminum dust that has a silvery color in the oil. So when you check the oil level, you may see something like a metallic sheen on the dipstick, but this powder should be just that, nothing more, a powder that cannot be turned into any other grain of aluminum.
But when engine bearings suffer from a lack of oil or overheating, they will scratch and form fine ribbons or chips. So when you check the level or change the oil, if you see aluminum strips or pieces in the oil or stuck to the dipstick, you probably have a worn or broken bearing.
4.- Copper luster in oil
There is also a copper sheen in the oil. Many bearings are designed with 3 layers: steel back plate, copper layer in the middle and soft aluminum outer layer. Because copper is softer but more slippery than aluminum, it is used in these bearings to provide the owner with the last line of defense before the bearing hits the steel bed or stops completely.
The life of the copper layer is approximately 1,000 to 2,000 miles, giving you the opportunity to detect bearing problems before they damage your engine. When the bearing wears down to the copper layer, it will let you know by sending a warning signal in the form of copper specks in the oil.
