2. Worn Lifters/Camshaft: The lifters and camshaft are responsible for controlling the opening and closing of the engine's valves. Over time, these components can become worn or damaged, causing a ticking sound.
3. Valve Train Issues: Failure or misalignment of hydraulic lifters, push rods, rockers or valve train components can cause a ticking sound due to improper movement of engine parts.
4. Loose Timing Chain/Belt: The timing chain or belt synchronizes the movement of the pistons and valves. If it becomes loose or worn, it can cause a rattling or ticking noise.
5. Carbon Buildup: Over time, carbon deposits can build up on the valves and combustion chamber, leading to a ticking sound due to restricted airflow.
6. Damaged Injectors: Faulty fuel injectors can cause a ticking noise as they fail to properly spray fuel into the cylinders.
7. Exhaust System Leaks: A leak in the exhaust system, especially near the manifold, can produce a ticking sound.
