The dire consequences of an engine which lacks lubricating oil


An unlubricated engine would severely damage your car, and your pocket as well

Engine breakdown could come from the most unexpected reason- lubrication. This is because the consequence often comes gradually but not abruptly. For example, a dead battery will likely be dead right away, but un unlubricated parts could take longer to show signs of malfunction. But when it does, the effect is quite devastating.

The lubricating oil is like the synovial fluid between human joints, it is necessary for the device to work smoothly, and also it distributes the heat from the rod bearings and the pistol. Without it, the crankshaft will srub the ball bearings and wear it out in no time. The reasons might be a malfunctioned oil pump or a clogged pickup screen. Sometimes it can be caused by the rod bearing as well.

Lack of proper lubrication can inflict serious damage to other components

There is one kind of engine that's more vulnerable to oil deprivation, and that is the Overhead cam. The OHC type is more troublesome than the push-rod because the cam and the valve are positioned very far from the pump. Also, there is a delay between the moment you start the OHC engine and when the oil reaches the cam bearings. So when the oil becomes more viscous, it's hard for the lubricating oil to reach the bearings and so the cam bearing is deprived of oil. That's the reason why the 5W-30 type is recommended in almost all OHC-type engines because its viscosity doesn't change too significantly when the temperature is lowered.

One way to check if your car has this issue is to use the tool that's attached to it, the dipstick. Open it and see how much is still there. Also, check the intake valves, as well as the combustion chambers, for excessive soot stick to it.

If you witness the appearance of soot, it's possible oil was burnt by the engine. The reason might be an old piston ring and worn out cylinders that let oil leaks through. We recommend you to get a new valve and guide liners in this case, but if you really want to fix it, you can have the valve guides knurled so the clearance is shorter.

But it's not a sustainable solution, really. Because the solution is not fail-safe, you might get it wrong sometimes. A new valve seal, on the other hand, can get rid of this problem almost instantaneously. After you have done that, remember to change your oil regularly. Not only will it run better, but also the process of opening the engine to examine would help you get a more regular look at it, and thus prevent any arisen situation.
