Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before beginning work.

2. Remove Components

Tools Required: Socket set, wrench set
Disconnect the air intake duct and any electrical connectors attached to the intake manifold.
Remove the intake manifold by loosening the bolts and lifting it off carefully.
Remove the valve cover by unscrewing the retaining bolts and lifting it off.

3. Inspect and Replace Camshaft

Visually inspect the camshaft lobes and bearings for wear or damage.
If replacement is necessary, remove the camshaft by unbolting the camshaft caps in the correct sequence (refer to service manual for sequence).
Clean the camshaft journal surfaces thoroughly.
Install the new camshaft, ensuring it is aligned correctly with the timing marks.

4. Reassemble Components

Reinstall the valve cover using a new gasket to prevent oil leaks.
Reattach the intake manifold, ensuring all bolts are torqued to manufacturer specifications.
Reconnect the air intake duct and any electrical connectors.

5. Refill Engine Oil

Use the specified oil type and capacity as per the owner's manual.
Start the engine and let it run for a few minutes to circulate oil.
