timing belt maintenance
For many overhead cam (OHC) engines with a timing belt it is supposed to be replaced every 60K miles. Most OHC engines are interference engines and if the belt breaks or slips enough the valves will be damaged by the pistons. I prefer chains to belts but they should be located at the front of the engine and not at the rear requiring removing the block to replace them. Also, the chain "plastic" contact surface should be as reliable as the chain. My Alfa Romeo 2600 Spider had a good implementation.
