Frequently Asked Questions

What is the head-gasket?

A gasket is a sheet of metal that forms a strong seal in an engine. The head-gasket fits between the engine block and the cylinder head (the part of the engine over the cylinders)

What are the signs of a blown head-gasket?

Rough-running, overheating, bubbling sounds and a white mayonnaise- like deposit on the underside of the oil filler cap are likely signs of a blown head-gasket.

How much does a head-gasket repair cost?

The actual head-gasket itself is a relatively cheap part, usually less than £50, but there’s a lot of labour involved in the tear-down of the engine remove and change it, plus the reassembling. The average cost of a head gasket repaid is £350 or so, depending on where you are and the complexity of your engine.

What does a “blown” head-gasket mean?

It means that the seal between the cylinders and the rest of the engine has been broken. Most often it’s the seal between the cylinders and the cooling system that blows and this can lead to rough-running and overheating, which can cause lots of damage.

Can you use head-gasket sealers?

There are products available, but they’re a temporary fix at best and may even cause more damage by blocking your cooling system. its always best to have a repair or a replacement.

Can I drive with a blown head-gasket?

You can, but you shouldn’t. A blown head-gasket can lead to many problems, including serious overheating and the complications arising from coolant and oil mixing, which can damage bearings and camshafts.

Signs of a blown head-gasket

It’s not always possible to definitely identify a blown head-gasket yourself. You may notice an oil or coolant leak at the seam between the cylinder and engine block, or cylinder misfirings, overheating, or the “mayonnaise” caused by the emulsion of oil and coolant.

More about your head-gasket

Your head-gasket “seals” in the integrity, pressure and temperature within your engine. It also helps with the distribution of coolant and oil.

When your engine is running, your head-gasket has to operate in some high temperatures and pressures. Your car engine needs to be cooled constantly and so if the head-gasket is damaged, this leads to overheating. You’ll lose compression and water, oil and coolant will leak and mix together, causing a reduction in the cooling and lubrication functions. This is very bad news for your engine.

Several materials go into building your head-gasket as it needs to be resistant to heat, pressure, oils, coolants and other chemicals. The head-gaskets vary between makes and models of cars as a result.

While head-gasket repairs or replacements are expensive, you can look out for yours failing so that you catch it early enough to prevent knock-on problems caused by overheating.

Look out for:

  • Your engine overheating
  • Your temperature gauge being higher than normal
  • Milky-white oil
  • White smoke in your exhaust
  • Loss of coolant but no visible leaks
  • Oil or coolant on your spark plugs
  • Bubbles of air rising when you remove the radiator cap
  • A loss of power or “chugging”, and 
  • Oil in the water tank.

There are some other signs that are less obvious to the untrained eye, so it’s important that you head to a garage to get checked out.

Despite the expense of a head-gasket repair, it’s important that you get attention as soon as possible so that you don’t end up with more extensive – and expensive – repairs down the line.

About that expense

It really does vary depending on your location and your car make. A Mercedes, for example, will cost around £700 while a Fiat may cost around £350
