- Service manual for the S54
Step-by-Step Installation Process
1. Preparation
Before beginning the installation, make sure the engine is cool. Disconnect the battery and remove any engine covers to access the camshaft area.
2. Remove the Old Camshafts
Follow these steps to remove the existing camshafts:
- Remove the valve cover by unscrewing the bolts.
- Detach the camshaft timing chain or belt.
- Unbolt the camshaft caps and lift out the old camshafts carefully.
- Inspect the camshaft journals for wear and damage.
3. Install New Camshafts
Now it’s time to install the David Vizard-recommended camshafts:
- Clean the camshaft journals thoroughly.
- Apply a thin layer of engine oil to the new camshaft seals.
- Carefully place the new camshafts into position.
- Reinstall the camshaft caps, ensuring they are torqued to the manufacturer’s specifications.
- Reconnect the timing chain or belt, aligning it correctly.
4. Reassemble the Engine
After the camshafts are securely installed, reassemble the engine:
- Replace the valve cover and tighten the bolts.
- Reinstall any other components removed during disassembly.
- Reconnect the battery.
5. Final Checks
Before starting the engine, double-check all connections and ensure there are no tools left in the engine bay. Turn the ignition on without starting the engine to allow the fuel system to prime.
Testing the Upgraded Engine
Once the installation is complete, it’s essential to test the engine to ensure everything is functioning correctly. Start the engine and listen for any unusual noises. Monitor the engine temperature and check for any leaks.
Conclusion
Installing David Vizard-recommended camshafts on the S54 engine can significantly enhance performance, providing an increase of over 20 horsepower. With the right tools and careful attention to detail, this upgrade can be accomplished effectively, leading to a more exhilarating driving experience.
