So, head gasket leaks can cause a lot of problems with your vehicle. Consequently, the biggest problem caused by head gasket leaks is the loss of coolant. As a result, a low coolant level can lead to your engine overheating; which can quickly cause more damage. Also, leaks can cause problems with your engine. Because, coolant is drawn into the combustion chamber.

Furthermore, to make matters worse burning engine coolant; can foul your spark plugs. Also, engine coolant in your cylinders can; cause rust and corrosion to form on pistons and rings. As a result, causing loss of engine compression. Furthermore, If a head gasket is leaking; coolant and oil may mix resulting in damage to the engine’s bearings. Coolant and/or oil may also burn off; which can cause overheating or improper lubrication.

How To Tell If You Have Head Gasket Leaks:

  • Coolant leaking externally from below the exhaust manifold
  • Misfire on startup; if accompanied by a puff of white exhaust smoke
  • White smoke from the exhaust pipe
  • Bubbles in the radiator or coolant overflow tank
  • Overheating engine
  • Oil-contaminated coolant forms a mayonnaise-like film
  • Coolant-contaminated oil takes on a white frothy consistency
  • Fouled spark plugs
  • Low cooling system integrity

So, an internal coolant leak doesn’t always mean; the head gasket is leaking. Similar leaks can also be caused by; hairline cracks in the cylinder head or engine block.

Regardless of what type of head gasket is used or how carefully it is installed; some operating conditions can cause even the best head gasket to fail. So, pre Ignition/detonation is probably the most common cause of head gasket failures today.

Finally, all of these factors can lead to, permanent damage of the metal components in your engine.
