One of the most common causes of a blown engine is overheating. When an engine overheats, the metal components can expand and warp, causing them to fail. The most common cause of engine overheating is a lack of coolant, which can be due to a leak or a faulty water pump.
Loss of oil pressure
Oil is essential for lubricating the moving parts of an engine. If the oil pressure drops too low, the engine can seize up, causing catastrophic damage. The most common cause of a loss of oil pressure is a faulty oil pump or a blocked oil filter.
Detonation
Detonation, also known as engine knock, occurs when the fuel in the engine ignites too early. This can cause the engine to run rough and can eventually damage the pistons and connecting rods. The most common cause of detonation is a bad spark plug or a faulty ignition coil.
Hydrolocking
Hydrolocking occurs when water gets into the engine's cylinders. This can cause the engine to seize up, causing catastrophic damage. The most common cause of hydrolocking is a cracked cylinder head or a blown head gasket.
Mechanical failure
In some cases, a blown engine can be caused by a mechanical failure, such as a broken connecting rod or a failed piston. These types of failures are often the result of excessive wear and tear or a manufacturing defect.
