Will the Mercedes-Benz 271 timing chain cause valve damage if it breaks?

[LaLogan]

If the timing chain of the Mercedes-Benz 271 engine breaks, the camshaft will obviously not operate according to the timing. In this case, it is highly likely to cause collision between the valves and pistons, resulting in severe damage. Therefore, the timing belt must be replaced according to the mileage or time specified by the manufacturer. Generally, timing chains are not prone to breakage and have relatively long warranty periods. If maintenance records are complete and the failure is not caused by human factors, you can contact the 4S dealership to apply for warranty coverage. Timing chains are typically made of alloy materials and operate inside the engine with oil lubrication. Their service life can theoretically last until the vehicle is scrapped. However, the chain tensioner also has a normal wear lifespan and should be inspected and replaced when necessary. Compared to the cost of replacing a timing belt kit, the price of tensioner components is naturally much lower.
