The Best Way to Deal with Cylinder Head Cracks


Cracks in your cylinder head are devastating to both your engine and wallet. In most cases, it’s not just the cylinder head that is damaged. The problem with your Porsche or BMW could be more significant than initially expected. Fortunately, the majority of cylinder head cracks are fixed easily.

What Causes Cylinder Head Cracks?

Cylinder head cracking is a common problem generated by excessive heat. Although not visible to the naked eye, engines expand and contract as it heats up and cools back down. Rapid temperature changes cause much stress on the cylinder head. Advanced metal compositions can make the head more resilient to cracking, but it is still not entirely avoidable. In addition, combustion engines on high-performance vehicles generate much heat as they provide enormous amounts of power to the transmission system.

Porsche and BMW vehicles are known for their agility and power. However, power can sometimes come at a cost. When engine components fail, it leads from one thing to another. For example, a faulty head gasket can stress the cylinder head and the engine block. These two components are often made of different metals to handle the immense combustion pressure. So when the head gasket fails, it often results in cylinder head cracks and other issues.

Several problems could result from cylinder head cracks. First, the coolant could seep through the cracks and enter the cylinder and engine block. While coolant leakage will not result in immediate catastrophic failure, severe damage is highly likely. Coolant could enter if the cracks are large enough, leading to power loss and damage to the piston and piston rings. The valves may also sustain damage if the cracks are situated nearby. Other engine issues may result without immediate repairs. Engine and cylinder repairs are costly if the problems have already worsened. Dealing with the problem early on prevents cracks from spreading and repair costs down. 

By no means are cylinder head cracks tolerable. They obviously won’t be going away on their own. Also, cracks can expand when left unattended. That’s why you need to have your car checked soon as you notice signs of cylinder head problems. You may visit our shop for cylinder head repair in Torrance, CA.

Professional Cylinder Head Repair

There’s no possible way to DIY your way around cylinder head issues. Even if you have welding machines lying around, they won’t guarantee the integrity of your cylinder. A professional mechanic needs professional equipment to locate and identify all cracks. The process also involves checking how deep the crack goes. A technician can also determine if the cylinder head is still salvageable. Some cylinder head cracks cause so much damage that the entire part is irreparable. In these cases, replacing the head is the best option.
