What are the Symptoms of a Blown Head Gasket?

Your car's head gasket is a very important component of your engine block. It is the part that ensures that engine fluids (fuel, oil, etc.) never mix. The head gasket is tightly sealed and is designed such that it will stop residue buildup to protect the engine from things that might cause an explosion. If your head gasket is damaged, your car will have a lot of problems.

Here are the most common signs of a blown head gasket.

1. Malfunctioning Cylinders

Any misfiring from your vehicle cylinders also shows the head gasket is damaged. The cylinder is where the fuel burns to power your vehicle. So if your cylinders misfire, it may indicate that there's a problem between two or more cylinders. You'll need an expert to carry out leak testing and cylinder compression to determine the cause of the problem.

2. Telltale Leaks

Any leaks from your engine are a clear sign that your head gasket is blown. The fluids in your car are supposed to be in an airtight (closed) system, so any fluid coming from the engine (other than from air conditioning) is a sign that there's an issue with the head gasket.

If the head gasket is blown, the coolant or external oil will find its way out via the seams, cylinder head, and engine block. The leaks show the head gasket has failed and needs immediate attention.

3. Blue exhaust smoke

Just like white exhaust fumes, blue exhaust smoke also indicates here an issue with the head gasket. Blue fumes are a sign that the head gasket has failed, and now the engine is combusting oil. The oil leaks from lubricating pistons and moves into the combustion chamber where it gets burned to produce blue fumes.

4. Startup Troubles

Your vehicle is designed so that it can start smoothly. If you have problems starting the car or you notice white smoke at the exhaust pipe, it could indicate that your head gasket has failed. The car runs through high-powered operations as it starts and cooling the cylinders is critical at this stage. If the startup operation can proceed smoothly, your head gasket could be the victim.
