Timing chain inspection and service for your Sprinter catches a stretched chain before it jumps time and wrecks the engine, which is the last thing a working fleet van needs. We check chain stretch with Xentry crank and cam correlation, listen for cold-start rattle, and replace worn chains, guides, and tensioners on OM642 and OM651 diesels. Catching wear early protects the whole engine.


## What this includes
- Xentry crank and cam correlation check for chain stretch
- Cold-start rattle assessment and running inspection
- Timing chain, guides, and tensioner replacement as needed
- Camshaft and crankshaft timing verified on reassembly
- New seals and gaskets at the front cover
- Oil and filter change after the chain work
- Post-repair scan and road test

## Who it is for
- You hear a chain rattle on cold start
- A camshaft correlation or timing code is stored
- Your high-mileage OM642 or OM651 is due for inspection
- You want to catch chain wear before it jumps time

## Pricing
Diagnostics run $285 per hour and chain replacement labor runs $260 per hour; an inspection versus a full chain, guides, and tensioner job sets the range, all in writing.

## FAQ
### How do I know if my timing chain is stretched?
A rattle on cold start, a camshaft correlation code, or a check-engine light are the warning signs. We measure crank-to-cam correlation with Xentry to confirm the stretch.

### Is a stretched chain urgent?
Yes. A worn chain can jump time and bend valves or worse. Catching it early with an inspection costs far less than the engine damage a failed chain leaves behind.

### Do you replace the guides and tensioner too?
Yes. We replace the chain, guides, and tensioner together, since worn guides are usually what let the chain stretch and reusing them invites a repeat failure.

### Which engines are prone to chain wear?
Higher-mileage OM642 and OM651 diesels can show chain and guide wear, especially when oil intervals get stretched. Regular oil service slows it down.
