Step 1: Check for Symptoms of a Blown Head Gasket
Before attempting to start a car with a blown head gasket, it is crucial to identify the symptoms of this issue.
This will help you determine the severity of the problem and whether it is safe to proceed. There are several common symptoms of a blown head gasket that you should look out for.
Mixed oil and coolant
One of the tell-tale signs of a blown head gasket is the presence of mixed oil and coolant.
When the head gasket fails, it can allow these two fluids to mix together, resulting in a milky substance. To check for this symptom, you can inspect the oil dipstick or the coolant reservoir.
If you notice a creamy or frothy consistency in either of these fluids, it is a strong indication of a blown head gasket.
Recurring engine overheating
Another symptom to watch out for is recurring engine overheating.
When the head gasket is compromised, it can cause coolant to leak out or prevent it from properly flowing through the engine. As a result, the engine may overheat frequently, leading to potential damage.
If you notice that your car is consistently overheating, even after allowing it to cool and adding coolant, it is likely that you have a blown head gasket.
Car not starting
In some cases, a blown head gasket can prevent the car from starting at all. This is due to the combustion gases escaping from the cylinders, resulting in a loss of compression and an inability to ignite the fuel.
If you have difficulty starting your car, especially after checking the battery and other possible causes, it may be a sign of a blown head gasket.
