Head Gasket Leaks

K-Seal provides a permanent repair for most head gasket failures.

What are the Symptoms of Head Gasket Failure?

If you don’t notice the early symptoms of head gasket leaks and continue to drive the car, things will get progressively worse. The symptoms of a head gasket failure are:

  • Radiator constantly needing to be topped up with water
  • Increased engine running temperature
  • Engine gauge showing maximum temperature after a few minutes
  • Cloud of exhaust fumes when the car is started or idling for a while
  • Plumes of smoke coming from the exhaust

The final, most noticeable symptom is a big cloud of smoke pouring from the exhaust, and the engine gauge showing maximum temperature after a few minutes. Unfortunately, these symptoms often arrive when it is too late to sort the problem out.

Taking this long to spot the problem will hit your wallet hard, because the only thing you can do is take the car to a mechanic and get a quote for replacing the gasket and associated engine damage. It’s not the cost of the new gasket that’s the problem – it’s the labour costs involved in stripping the engine. In some cases, the engine may have to be completely replaced because of excessive damage caused by prolonged heat exposure, thanks to the blown head gasket.

How Much Will Head Gasket Repair Cost at a Garage?

Repairing a blown head gasket is any motorist’s worst nightmare. With the cost of head gasket repairs running into thousands, it’s often easier and cheaper to scrap the vehicle than it is to have it repaired.

Unfortunately, head gaskets are prime candidates for failure and breakage due to the intensity of the job they perform, and they do tend to cost a lot to repair and replace. K-Seal will permanently repair and fix most head gasket failures but failing to do so early can lead to a much costlier fix.

The high costs involved generally stem from the amount of labour required to sort the problem out, rather than the cost of a replacement part, which is actually comparatively low. It’s an extremely time-consuming task because the engine head has to be removed and then replaced, and the more time a mechanic is forced to spend on that job rather than something else, the more they will charge you.

The cost of repairing or replacing head gaskets will ultimately depend on the speed at which the problem is identified. The longer you wait before going to the garage, the more you can expect to pay to get back on the road again. On that note, the garage you choose will also depend on how much you can expect to pay – while there shouldn’t be too much difference in the prices you will be advised to pay, it will probably be worth your time getting a few quotes from local mechanics so you can be sure of getting the best deal.

Can K-Seal Fix my Head Gasket?

When a head gasket blows or develops a leak, the entire engine is put at risk. This can be an extremely expensive problem to rectify, so it is vital that it is sorted out as soon as an issue is identified. K-Seal will permanently repair and fix most head gasket failures including:

  • Coolant to cylinder leaks
  • Cylinder to coolant leaks
  • Blown head gaskets
  • Coolant to oil leaks (in certain situations)

The best and most effective sealant products are manufactured by K-Seal. All of the leading roadside repair and recovery organisations use K-Seal technology because it mixes successfully with all kinds of antifreeze and engine coolant in order to repair failures, preventing combustion gases escaping and coolant leaking into the engine cylinder.

Tested independently by the engineering department of the University of Brighton to ensure that the products meet industry standards, K‑Seal, K‑Seal Ultimate and K‑Seal HD (designed for use in large vehicles such as HGVs and tractors) are the first choice of motorists on a global scale.

Is Head Gasket Sealant Safe to Use?

Generally, it is not recommended to add anything to your engine – because it’s such a complicated piece of machinery that works in a very precise way, even a small change to that could be disastrous for the entire thing. However, K-Seal head gasket sealant can be added to the coolant solution without damaging the engine at all and without leaving any debris floating in the solution once it has done its job.

  • The K-Seal formula features a unique blend of chemical ingredients including ceramic microfibres and copper particles which acts to seal holes and imperfections in head gaskets.
  • If coolant is leaking from the engine, the sealant will follow the coolant through the gap and close it up, with the microfibres and particles meshing together inside.
  • This mesh, when it is exposed to both the gases within the combustion chamber and the heat of the engine, fixes together and seals the hole, restoring the gasket to full health and allowing it to continue doing its job in the face of high pressure and temperature.
  • Because the particles are so small, they can only seal holes that are up to 0.635 mm in diameter, so if they manage to find their way down passages in the heater core or radiator, they won’t have any effect on them (Proven in independent university testing).
  • This negates any possible chance that the sealant could inadvertently damage other parts of the engine.

With this in mind, it is clear that there is no risk to the car engine as a whole, regardless of how big it is or the type of fuel it needs in order to run. It is, in fact, completely safe to use K-Seal in almost any vehicle engine, from motorcycles to commercial vehicles, so you don’t have to worry about suddenly being left without transport regardless of what you’re driving.

What is a Head Gasket?

A head gasket has one of the trickiest but most vital jobs within a car’s engine. It is the seal between the engine block and cylinder head, exposed to both high and low pressure levels in addition to a wide range of temperatures. It seals the combustion gases within the engine and keeps out the coolant that is designed to cool the engine cylinder.

How Does a Head Gasket Work?

A head gasket only works as long as the compression seal is intact – the fact that nothing can get past the seal ensures that the engine works perfectly. This is why a leak in that seal can be so devastating for the car’s performance in both the short and long-term.

Why Do Head Gaskets Fail?

Head gaskets perform a task which puts an incredible amount of stress on them, so it’s not surprising that some will fail. However, this can potentially be disastrous as far as the drivability of the car is concerned. There are two major ways the head gasket can fail:

  • Letting combustion gases leak out
  • Letting coolant leak in

If the combustion gases leak out, the engine’s performance drops. If the coolant leaks in, it won’t be going round the cooling system, meaning the engine will overheat.
