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.

Because, a low coolant level, can lead to your engine overheating. And, that can quickly cause even more damage.

And, if coolant is drawn, into the combustion chamber, that’s when head gasket leaks, are the worst.

So, 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, causing damage to the engine’s bearings. Coolant and/or oil may also burn off, which can cause, overheating or lack of lubrication. But, not head gasket leaks.

What Are The Most Common Signs Of 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 recovery 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, you have head gasket leaks. 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.

As a result, all of these factors can lead to, permanent damage of the metal parts in your engine. So, head gasket leaks, can be external or internal. Consequently, external, you can usually see the leak. However, internal leaks are bad, because, you don’t even know where to look.
