Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, compression tester, engine oil, safety glasses, gloves.
Disconnect the battery to ensure safety while working on the engine.

2. Remove Engine Cover

Use a socket set to remove the bolts securing the engine cover.
Carefully lift the cover off and set it aside.

3. Inspect Camshaft

Visually inspect the camshaft for wear, scoring, or damage.
Rotate the engine to ensure the camshaft is turning properly and is not binding.

4. Replace Camshaft (if necessary)

Tools Required: Camshaft holding tool, torque wrench, new camshaft, new gaskets (if applicable).
Remove any components obstructing access to the camshaft (timing belt/chain, rocker arms, etc.).
Use the camshaft holding tool to secure the camshaft in place.
Remove the bolts securing the camshaft using a torque wrench, noting the torque specifications for reinstallation.
Carefully lift the faulty camshaft out and replace it with a new one, ensuring proper alignment.
Reinstall all removed components, ensuring they are torqued to the manufacturer's specifications.

5. Reassemble Engine

Reattach the engine cover and secure it with bolts.
Reconnect the battery.
