Why A Car Engine Blows: 5 Common Causes-

The following are some causes that may cause a car’s engine to blow:

  1. Failure to maintain your car regularly– Lack of regular maintenance can harm your car’s engine by enabling parts like the timing belt, oil filter, and spark plugs to get dirty, or fail. This can result in decreased performance or even a blown engine.
  2. Engine overheating- According to research, overheating is the third most common cause of engine damage.

In addition, if the engine overheats, the head gasket may break, enabling coolant and oil to mix, causing more harm to the engine and increasing the risks of a blown engine.

  1. Applying poor-quality motor oil- Applying low-quality or the wrong kind of motor oil can cause damage to a car’s engine. That’s because it fails to properly lubricate and regulate the engine temperature. 

In a survey, it was shown that 27% of drivers are unaware of the sort of oil their vehicles need.

  1. The car’s engine seizes- A shortage of oil or coolant, lack of maintenance, and significant stress on the engine might cause it to seize up and eventually fail.
  2. Defect in the timing belt– Timing belts are normally made of rubber, but with time, heat exposure and other environmental factors can cause them to deteriorate.

If the timing belt breaks, the camshaft and crankshaft may become  unsynchronized. This could result in valves colliding with the engine’s pistons and might cause cracked engine blocks, deformed valves, and broken pistons.
