If the timing chain becomes stretched, it may lead to engine noise and jump timing, meaning that the relative position of the camshaft and crankshaft sprocket falls out of specification because a tooth on a sprocket has been skipped. Maintaining consistent levels of the right kind of motor oil and completing regular oil changes can help lubricate and protect your vehicle's timing chain and sprockets to prevent corrosion, stretching, and damage from metal-on-metal contact.

Timing chains are designed to withstand extreme temperatures and demands, but need proper oil levels as well as a healthy tensioner and chain guides for proper chain-to-sprocket tooth fitment and operation. Timing chain sets usually include the crankshaft and camshaft sprockets, timing chain, and any guides, rails, or tensioners necessary for a complete timing chain replacement. Over the life of the vehicle, or due to low oil levels, the timing chain, sprockets, or other parts may suffer wear and need to be replaced. Timing chains were most common on older vehicles, but continue to be used even in modern vehicles as they provide the most durable timing solution with minimal maintenance. A gear on the crankshaft drives the camshaft sprocket(s), allowing the camshaft to open and close the valves during the proper piston stroke to start and run a vehicle. The timing chain serves as a link between your crankshaft and camshaft(s) to assure the rotating assembly and timing components of your engine are in time.
