Timing chain kit

How you know it is this

• A rattle from the front of the engine on a cold start
• A timing correlation fault code
• Plastic fragments found in the sump or the oil strainer

Worth knowing before you buy

• NEVER FIT A CHAIN ALONE. The tensioner and the plastic guides wear with it, and a new chain on old guides is back within a year. That is why this is sold as a kit.
• The labour is most of the cost on this job — the front of the engine comes apart, or on some engines the gearbox comes out. Doing it once with every part renewed is the cheap way.
• Kits vary in what they include. Confirm whether the sprockets, the camshaft adjusters and the cover gaskets are in yours before ordering.
• A stretched chain does not snap; it jumps a tooth, and then the valves meet the pistons. The rattle is the warning.

Rest of the service kits

• Service kit A / B
• Major service kit
• Brake service kit (pads, discs, sensors)
