Symptoms: Power Loss
Why is my car losing power?
Loss of power or difficulty accelerating, often alongside other symptoms such as white smoke from the exhaust and low coolant levels, can be a symptom attributed to a blown head gasket.
How is a lack of power caused by a blown head gasket?
The head gasket is inside the engine, and forms a seal between the combustion chamber, which contains highly compressed gasses, and the rest of the system.
When the head gasket sustains damage or ‘blows’, the seal between the highly compressed gasses and the cooling system and other internal engine networks is broken, allowing the gasses to escape.
This means there is less gas compression inside the combustion chambers. Compression is critical to the reactions which take place inside an engine to help it run, so when the gasses escape and compression is lost, the reactions are less efficient. This results in an engine which is not running smoothly and cannot function as normal, resulting in a lack of power.
Why should I fix my blown head gasket?
If the lack of power is caused by a blown head gasket, there will be other problems caused by the internal engine damage which will only become worse as time goes on. Meanwhile, a vehicle running on less power due to a serious internal fault is not safe to be on the roads, as both acceleration and vehicle reliability are compromised and need to be fixed as soon as possible. Have a look at what can happen if you don’t repair your blown head gasket.
Compression inside the combustion chambers of the engine is critical to the running of the engine. Eventually, as more gasses escape, the seal will break more and more until there is very little or no compression in the combustion chambers. At this point, the vehicle will not start and no pour-in head gasket fix will be able to help.
Damage to other engine components
An engine operating on low compression can invite further damage to its internal components, with cylinder heads and other combustion components warping and causing damage to themselves without highly compressed gasses to keep them operating as smoothly as they could.
My car is low on power. What should I do?
If you have noticed your car has less power, either consistently or intermittently, it is always best to have the problem diagnosed by a mechanic. If this symptom is accompanied by others such as steam escaping the exhaust, loss of coolant or a creamy liquid on the oil filler cap, it is highly likely that the problem is a blown head gasket. While it should still be diagnosed by a mechanic, begin to research your head gasket repair options.
