FAQ

Frequently Asked Questions

No. A timing gear is a metal cogwheel, while a timing belt is a reinforced rubber belt. Both serve the same synchronising function but in different engine designs.

Almost never. It is a highly specialised technical term. Using it figuratively would be very rare and likely confusing.

In an 'interference' engine design, failure can cause the pistons to collide with the valves, resulting in severe, often catastrophic, engine damage.

Metal timing gears are generally very durable and often last the lifetime of the engine, unlike timing belts which have scheduled replacement intervals.
