The ticking noise is caused by the lack of oil, which results in the engine's components rubbing against each other.
* Worn-out oil filter:
The oil filter is responsible for removing contaminants from the oil, and when it becomes worn out, those contaminants can cause the engine to tick.
* Loose or worn-out timing chain:
It regulates the timing of the engine's valves. When the timing chain becomes loose or worn out, it will not be able to keep the valves in sync, causing them to collide with the pistons and create a ticking noise.
* Faulty hydraulic lifters:
These are small devices that help to reduce friction between the camshaft and the valves. When they become faulty, they will not be able to do their job properly and the valves will make a ticking noise.
* Carbon build-up:
Can occur on the valves and cause them to stick. When the valves stick, the engine will not run properly and will produce a ticking noise.
