This blog, in addition to the usual maintenance details for classic mini cars, an attempt is made to explain the "whys" and "wherefores" of the various jobs.

Refitting the Plugs

Make sure the sealing washers are not flattened and screw the plugs home by hand, using the plug spanner only for the final half-turn to ensure a gas-tight joint. Overtightening is unnecessary and likely to lead to trouble. If the plugs cannot be screwed in by hand, ask the local garage to clean-up the threads in the cylinder head with a plug thread tap.
