Repairing Your Head Gasket
The images below show what's involved in repairing a cylinder head gasket, from the initial strip down to re-assembly. Modern engines are fairly complicated, with numerous additions to help the engines efficiency, smoothness and control. However, the task is fairly straight forward, it just takes time, energy and some mechanical engineering ability. If you're not planning to do the job yourself, the images may give you an idea on what is involved and why garage costs can be high.
The vehicle in this example is a 2.5 litre, 5 cylinder Land Rover TD5 diesel engine, so it's of a reasonable size and weight. An engine hoist is used to lift the cylinder head off, as the head still has lots of ancillary components attached, (I have seen others lift this size head off by hand). Smaller engines should be no problem weight wise.

Main Tasks Required to Replace the cylinder head Gasket
The following is a rough list of the steps required to remove the engine cylinder head.
- Disconnect the battery, drain the water.
- Remove ancillary equipment (covers, brackets, pipes, hoses, cables, cooling fan, turbo, fuel lines etc) and any other items that may be in the way. This can be the task that takes the most time.
- Remove any associated fixing bolts, camshaft cover and cylinder head bolts.
- Lift off the cylinder head.
- Check the cylinder head and block for damage, clean.
- Have the cylinder head skimmed and overhauled (if necessary).
- Fit a new cylinder head gasket.
- Replace the cylinder head (reversal of dismantling).
