Frequently asked questions about head gasket repair & replacements in Cardiff

Read our answers to questions about head gasket repair costs, symptoms and more.

What does a cylinder head gasket replacement in Cardiff involve?

There are differences between engines on the exact process and components, but the typical engine will require most of the following basics to be done

  • Mechanic will check that the head gasket is faulty.
  • The engine will be drained of oil and coolant.
  • Components will be removed to allow access to the rocker cover and ultimately, the cylinder head bolts.
  • The engine timing will be locked in place using specifically designed pins and locking tools.
  • The timing belt will be removed, or the timing chain loosened off and moved off the camshaft sprockets.
  • The cylinder head will then be undone in a specific sequence.
  • Once all the bolts are out, the cylinder head will be removed and the surface of the engine block and cylinder head will be cleaned of all residue of the old gasket.
  • In the case of the majority of cylinder heads, it will need to be pressure tested to ensure it’s structure is sound and then go through a process called skimming. This process ensures that the surface that the new gasket will come into contact with is perfectly flat and clean.
  • Once the mechanic has completed the work on the components, the engine is reassembled with a new cylinder head gasket.
  • If the engine’s camshaft(s) are driven by a timing belt, this belt will be renewed along with a new water pump if it is on the timing belt circuit.
  • Once the engine is back together, the cooling system will be refilled and the oil replenished along with a new filter.
  • If the oil has become contaminated with the coolant, an additional oil flush may be required and likewise, if the cooling system has become contaminated, the cooling system will be flushed.
  • Once everything is back together, the mechanic will run the engine.
  • Finally a road test will ensure that everything works as it should when the engine comes up to temperature and finally any error codes present will be cleared down and re-checked.

As we mentioned previously, this is not a full exhaustive list of what will be done as each engine has its own requirements.

What are the symptoms of a blown head gasket?

In most cases the symptoms of a cylinder head gasket are pretty apparent, some however take a little know how and some tools to confirm. Typical symptoms though are;

  • A cream-like colour and consistency in the oil (usually seen on the engine oil dipstick) or in the cooling system header tank.
  • Coolant overflowing out of the cooling system header tank.
  • An unexplained loss of coolant.
  • Difficulty in starting the engine.
  • Evidence of exhaust gasses in the cooling system.
  • Poor engine compression.

How long does it take to change a head gasket?

The time it takes to carry out a head gasket replacement can range from 5 hours to more than a day.
