What is a Head Gasket?

As its name implies, a head gasket is a kind of seal or gasket placed between your car engine’s block and the cylinder head. Your car engine is sometimes referred to as the heart of the car because it is where internal combustion takes place.

High compression pressure rates are required for internal combustion to take place in the piston chamber. This high pressure is achieved because the head gasket is responsible for sealing the cylinder in the engine, allowing the compression to take place.

The sealing action provided by the head gasket makes certain that the vaporized gas contained in the engine will not leak out and cause problems. Another responsibility of the head gasket is preventing the leakage of either engine oil or coolant in the combustion chambers and preventing them from mixing together.

7 Common Blown Head Gasket Symptoms

  • Blown Head Gasket Symptom #1 – constant overheating of the engine. This symptom can actually be checked easily from your car dashboard’s temperature gauge reading. Engine overheating is likewise considered both a symptom and a cause of blown gasket heads.
  • Blown Head Gasket Symptom #2 – a considerable drop in the level of engine coolant.
  • Blown Head Gasket Symptom #3 – loss of engine power is also a possible indication of a blown head gasket because engine power decreases if there is a loss of compression. Likewise, the engine will not run as smoothly or as efficiently.
  • Blown Head Gasket Symptom #4 – engine oil and coolant mixing together. To check for this, inspect your engine oil to see if the dipstick comes up with a somewhat frothy, which can signal the mixture of coolant and engine oil that resulted from a damaged head gasket.
  • Blown Head Gasket Symptoms #5 – a milky substance around your oil cap, which means that the oil is contaminated. This happens when engine coolant mixes with the oil because of a gasket leak. To check, you have to drive your car for a bit and then inspect the oil cap.
  • Blown Head Gasket Symptoms #6 – white smoke comes out of your exhaust pipe and is accompanied by a sweet scent.
  • Blown Head Gasket Symptoms #7 – abnormal coloration around your spark plugs can also be a sign that you have a blown head gasket. If you have a serious problem with your head gasket, the coolant will leak out of the plugs’ holes. For example, if your engine coolant is orange, your spark plugs will also have an orange tinge around the plugs.

If your car is experiencing any of these symptoms and you think that you have a blown head gasket, you should immediately go to a mechanic. Now that you understand how critical your head gasket is to the overall working condition of your car engine, you understand why you need to allow a qualified professional to conclusively diagnose and fix the problems with your head gasket as soon as possible.
