Piston to valve clearance.
In the event of a cam belt or timing chain failiure
an engine classed as interference wil suffer considerable damage
when the belt/chain fails the valve timing goes out of sync
which causes the valves to contact the pistons,
resulting in bent/broken valves, possible damage to the valve guides located in the cylinder head, and very rarely damage to the pistons.
A non interference engine,also known as a freewheeling or safe engine.
In the event of belt/chain failiure, the valves do not meet the pistons
I:E the engine fails safe
A precautionary compression test should be carried out after belt/chain replacement
to check condition of the valves.
