  • Engine noise: rattling or ticking sound
  • Reduced engine power
  • Rough idle
  • Check the engine light on

Preventive Measures

  • Regular oil changes: Fresh, high-quality oil is key.
  • Avoid overheating: Keep an eye on your temperature gauge.

Diagnosis and Repair

Diagnosis Process
  1. Visual Inspection: A mechanic will start by visually inspecting the timing chain and related components for wear and tear.
  2. Sound Diagnosis: Listening for a rattling or ticking noise, especially during startup.
  3. Scan for Trouble Codes: Use of diagnostic equipment to read any engine codes related to timing.
  4. Timing Chain Tension Check: Manually inspecting the tension of the timing chain.
Repair Process
  1. Disassemble the Front of the Engine: Remove necessary engine parts to access the timing chain.
  2. Remove Old Timing Chain: Take out the worn or stretched timing chain.
  3. Install New Timing Chain: Place the new timing chain, making sure it’s properly aligned.
  4. Reassemble and Test: Reassemble the removed parts and test the engine for any timing-related issues.

Spark Plug Blowout

A spark plug blowout can occur due to improper tightening or engine overheating. It can lead to severe damage to the cylinder head and piston.


  • Engine misfire
  • Rough idle
  • Reduced engine power
  • Increased fuel consumption
  • Check the engine light on

Preventive Measures

  • Proper spark plug tightening: Ensuring snugness prevents blowouts.
  • Quality spark plugs: Invest in the good stuff.

Diagnosis and Repair

Diagnosis Process

  1. Visual Inspection: Check spark plugs for signs of wear or damage.
  2. Engine Misfire Codes: Use a diagnostic tool to check for misfire codes.
  3. Compression Test: To ensure no damage to the cylinder after blowout.

Repair Process

  1. Remove Damaged Spark Plug: Carefully remove the blown-out spark plug.
  2. Inspect Cylinder Head: Check for damage to the threads in the cylinder head.
  3. Insert New Spark Plug: Properly align and torque the new spark plug into place.
  4. Test Engine: Run the engine to make sure the new spark plug is functioning correctly.

Piston Slap

A piston slap occurs when pistons are loose within the cylinders, causing a range of performance issues.


  • Engine noise: slapping or ticking sound
  • Reduced engine power
  • Increased fuel consumption
  • Check the engine light on

Preventive Measures

  • Quality oil use: Always opt for quality oil.
  • Avoid overheating: Keep that engine cool!

Diagnosis and Repair

Diagnosis Process
  1. Sound Diagnosis: Listen for slapping or ticking noises during engine idle or acceleration.
  2. Compression Test: A test to measure each cylinder’s compression level.
  3. Disassemble for Inspection: If necessary, disassemble the engine to visually inspect the pistons.
Repair Process
  1. Engine Disassembly: Take apart the engine to access the pistons.
  2. Replace Pistons: Install new, well-fitted pistons.
  3. Reassemble and Test: Put the engine back together and run tests for any piston slap sounds or other issues.

Oil Leaks

Oil leaks can come from various parts of your engine, such as the valve covers, timing chain cover, and oil pan.


  • Oil spots under the vehicle
  • Reduced oil level
  • Check the engine light on

Preventive Measures

  • Regular engine inspection: Be proactive.
  • Tightening loose parts: Don’t let a loose bolt cost you.

Diagnosis and Repair

Diagnosis Process

  1. Visual Inspection: Look for oil spots under the vehicle and around the engine.
  2. Oil Level Check: Monitor the oil level using the dipstick.
  3. Pressure Test: Sometimes conducted to identify the exact location of the leak.

Repair Process

  1. Identify the Source of the Leak: Pinpoint the leaking part, such as a gasket, seal, or bolt.
  2. Replace or Repair Leaking Part: Remove the faulty part and install a new one.
  3. Test: Run the engine and check for any signs of leaking.
