What Causes the Ticking Sound in a Honda Accord Engine?
1 Answers
1. Clearance: When the engine is cold, the clearance between the cylinder wall and the piston has not yet reached the optimal size, and the lubrication from the engine oil is insufficient. Typically, when the engine block temperature reaches around 95 degrees, the sound will return to normal. 2. Engine Oil Issues: Using low-quality engine oil, not changing the oil for an extended period, or having insufficient oil can all increase friction between the valves and guides, as well as hydraulic lifters, making various engine noises more pronounced. Common Engine Problems in Cars 1. Starting System Failures Preventing the Engine from Turning or Turning Too Slowly: Insufficient battery charge, loose or severely oxidized battery terminal clamps; blown main circuit fuse; faulty ignition switch; starter motor issues; open circuit in the starting wiring or poor connector contact. 2. Ignition System Failures: Defective ignition coil leading to weak or no high-voltage spark; faulty ignition module; incorrect ignition timing.
