A head gasket has one of the trickiest but most vital jobs within a car’s engine. It is the seal between the engine block and cylinder head, exposed to both high- and low-pressure levels, in addition to a wide range of temperatures. It seals the combustion gases within the engine and keeps out the coolant that is designed to cool the engine cylinder.
A head gasket only works as long as the compression seal is intact – the fact that nothing can get past the seal ensures that the engine works perfectly. This is why a leak in that seal can be so devastating for the car’s performance in both the short and long-term.
Head gaskets perform a task which puts an incredible amount of stress on them, so it’s not surprising that some will fail. However, this can potentially be disastrous as far as the drivability of the car is concerned.
There are two major ways the head gasket can fail:
If the combustion gases leak out, the engine’s performance drops. If the coolant leaks in, it won’t be going around the cooling system, meaning the engine will overheat, and could lead to a blown head gasket.
Taking too long to spot the problem will hit your wallet hard with expensive head gasket repair costs. The only thing you can do is take the car to a mechanic and get a quote for replacing the gasket and associated engine damage.
However, there are a number of common symptoms you can keep in mind to help you diagnose this issue long before it gets to that point. If you do, then luckily there’s an easy way to fix a blown head gasket without replacing it.
