How to Repair Your cylinder head Gasket

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.
