Mercedes considers the timing chains on their engines to be a lifetime item, that doesn't need to be replaced. However, enthusiasts tend to know a little better. The first questioned asked when looking for a high mileage car for sale is “Do you know when the chains were done?” Any Mercedes owner knows that if the chains are not maintained and timing service done, headaches can be expected in the future.

With no service interval to go by, you need to pay attention to the chains. The first symptom is noise in the timing system. The chains slap around because of worn tensioners and guides. The common sound is “marbles in a can.” Failed guides can cause the chains to jump, skip a tooth and potentially snap.

The experts at VIEROL have assembled a kit for you to take care of this common problem.
