Are you aware of the signs that your Mercedes will show if the cylinder gasket head is already worn out or is failing? If your answer is no or you’re not if you’re conversant with the symptoms, then this guide is for you. The cylinder head gasket is a form of a seal that connects the cylinder head with an engine block.

This gasket seals your engine properly to create essential compression and prevent coolant and oil from combining. When it fails, it can lead to major engine problems. If you are aware of what these signs are as early as possible, you will not have to suffer a lot of discomfort and expenses. Let’s see some of the common signs of failure in your Mercedes and the steps to fix the gasket failure issue.

Main Symptoms of a Failing Cylinder Head Gasket

  • Overheating Engine: The first symptom of a failing cylinder head gasket is that the engine may tend to overheat. A broken gasket lets coolant enter the combustion chamber or mix with oil which weakens its temperature control function. You need to examine your cylinder head gasket if your engine heats up repeatedly despite having enough coolant.
  • White Smoke from the Exhaust: If you see white smoke coming out of your exhaust then be prepared to take your Mercedes to the workshop for a new head gasket. This is because when coolant gets into the combustion chamber it burns up. Whenever the coolant of your vehicle burns, it usually gives off a sweet smell alongside the smoke. If you observe white smoke or a sweet smell, do not waste time taking your Mercedes to an expert technician.
  • Loss of Coolant with No Visible Leaks: If your Mercedes is losing coolant but you don’t see any signs of leakage externally, then chances are that you have a faulty cylinder head gasket. It can seep internally, into the engine block or the combustion chamber where it evaporates and is almost invisible.
  • Milky Oil or Foam Under the Oil Cap: A bad head gasket lets coolant combine with engine oil and turns the fluid milky when you check it. You will see milky oil when looking at your oil cap or while using the dipstick. When oil is contaminated it ceases to have its lubricating capability and if not fixed your engine can suffer huge damage.
  • Loss of Engine Power: A blown head gasket is also likely to influence the compression in your engine and affect performance. If your Mercedes moves slowly, is hard to accelerate, or loses power it can be due to the head gasket.
  • Check Engine Light: Although the engine check can alert the driver to numerous problems, it generally comes on when the engine experiences problems associated with compression or incorrect fuel burning, which is characteristic of a bad head gasket. A diagnostic tool can tell whether the cylinder head gasket is the problem or not.
  • Bubbling in the Radiator or Coolant Reservoir: When the head gasket leaks, exhaust gases may get into the cooling system which consequently results in the fizzing of the water in the radiator. This is usually followed by increased temperature and reduced cooling ability of the car’s cooling system.

What to Do If You Think Your Car’s Head Gasket Is Failing

  • Seek Professional Diagnosis: Suspecting a bad head gasket is one thing and diagnosing it another because it needs special tools and knowledge. A professional technician can run some diagnostics including a compression test or a coolant system pressure test to be sure if the gasket is truly faulty.
  • Repair or Replace the Gasket: Most of the time, the cylinder head gasket will require replacement. This includes the process of taking off the cylinder head, cleaning the surfaces to be mated and fitting a new gasket.
