Timing Chain Repair

What Is a Timing Chain?

A timing chain serves the same basic purpose as a timing belt: it keeps your engine’s crankshaft and camshaft in sync, ensuring that valves open and close at precisely the right times during each cylinder’s intake and exhaust strokes. Unlike rubber timing belts, timing chains are made of metal and are built to last longer—often the entire lifespan of the engine. However, timing chains are still subject to wear, tension failure, or stretching. Because the timing chain plays a critical role in engine function, any issue with it can lead to serious engine problems. That’s why proper care and repair by the professionals at B and B Autohaus is so important.

Even though timing chains are more durable than belts, they still require periodic inspection—especially as your vehicle racks up mileage. If your engine starts running rough or making unusual noises, it might be time to have the timing chain inspected.

Symptoms of a Bad Timing Chain

Timing chains are generally reliable, but they’re not immune to problems. Here are some signs that your timing chain might need attention:

Engine Misfires or Runs Rough: A stretched timing chain can throw off the engine timing, leading to misfires, rough idling, or even stalling.

Metal Shavings in the Oil: As the timing chain wears down, it may begin shedding metal fragments. If these show up during an oil change, it’s a red flag.

Rattling Noise from the Engine: One of the most common symptoms of a failing timing chain is a rattling sound, especially during startup or acceleration. This could mean the chain is loose or the tensioner is worn.

Check Engine Light Comes On: If your vehicle’s onboard diagnostics detect timing issues, the check engine light may illuminate. A diagnostic scan at B and B Autohaus will help pinpoint the issue.

Difficulty Starting or Poor Performance: If the timing chain skips a tooth or more, your engine may struggle to start or experience reduced power and fuel efficiency.

What Happens if a Timing Chain Fails?

A broken or severely worn timing chain can cause catastrophic engine damage—especially in interference engines where pistons and valves occupy the same space at different times. If the chain fails while the engine is running, the results may include:

• Bent valves
• Damaged pistons
• Broken camshaft
• Complete engine failure

If you notice any warning signs, don’t wait. Bring your vehicle to B and B Autohaus in San Diego for a professional inspection.
