my Honda CR-V has a knocking noise when I accelerate what's causing it

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the battery to ensure safety during repairs.

2. Engine Oil Check and Change

• Sub-steps:
  1. Remove the oil dipstick and check the oil level; top off or change if necessary.
  2. If changing oil, place an oil drain pan under the oil pan and remove the drain plug using a socket set.
  3. Allow old oil to drain completely, then replace the drain plug and torque it to manufacturer specifications (typically around 15-25 ft-lbs).
  4. Remove the oil filter using an oil filter wrench and apply a thin layer of new oil to the rubber seal on the new filter.
  5. Install the new oil filter and tighten it according to specifications.
  6. Refill the engine with the recommended oil type (typically 0W-20 or 5W-20) and check the level again.

3. Inspect and Replace Spark Plugs

• Sub-steps:
  1. Remove the ignition coil cover if applicable and disconnect the ignition coils.
  2. Use a spark plug socket to remove the spark plugs; inspect for wear or damage.
  3. Replace old spark plugs with new ones, ensuring the gap is set to manufacturer specifications (usually around 0.044 inches).
  4. Reinstall the ignition coils and cover.

4. Engine Mount Inspection and Replacement

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Visually inspect all engine mounts for cracks or excessive wear.
  3. If any mounts are damaged, remove the bolts securing the mounts to the engine and frame using a socket set.
  4. Replace the damaged mounts with new parts, ensuring proper alignment.
  5. Torque the bolts to the specified settings.
