Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical issues during repair.
Allow the engine to cool before proceeding.

2. Change Engine Oil and Filter

Sub-steps:
1. Drain the old engine oil by removing the oil drain plug; allow it to fully drain into a suitable container.
2. Replace the oil filter using an oil filter wrench; lubricate the new filter's rubber O-ring with clean oil before installation.
3. Reinstall the oil drain plug and tighten it to the specified torque (typically 25 Nm or 18 lb-ft).
4. Fill the engine with the recommended oil type (e.g., BMW Longlife-01 or Longlife-14) to the correct level.

3. Inspect and Replace Hydraulic Lifters (if necessary)

Sub-steps:
1. Remove the engine cover by unbolting it and disconnecting any hoses or electrical connections.
2. Remove the valve cover by unbolting it, noting the order of the bolts for reassembly.
3. Carefully remove the hydraulic lifters using a lifter puller tool, taking care not to damage surrounding components.
4. Inspect the lifters for wear or damage; replace any that are defective with OEM or equivalent lifters.
5. Reinstall the valve cover with a new gasket to prevent leaks, and torque the bolts to the manufacturer's specifications (typically 10 Nm or 7.4 lb-ft).
6. Reconnect any hoses and electrical connections, and reinstall the engine cover.
