If you’ve heard a knocking o r ticking noise from your Toyota Hilux engine, it’s important to identify the cause as it could indicate a serious issue. Common causes include:

Low Oil Pressure: Low oil levels o r poor oil circulation can lead to insufficient lubrication, causing engine components to make a knocking sound. This can be resolved by checking and topping up the oil o r addressing any leaks o r oil pump issues.

Bad Fuel: Poor quality o r contaminated fuel can cause knocking sounds, as it may not burn properly in the engine. Switching to higher-quality fuel o r cleaning the fuel system could help resolve this issue.

Worn-out Engine Components: Over time, parts like pistons, connecting rods, o r valve lifters can wear down, causing a ticking o r knocking sound. If this is the case, the affected components may need to be repaired o r replaced.

Pre-ignition o r Detonation: This occurs when the air-fuel mixture ignites too early, causing a knocking noise. It could be related to incorrect spark timing, low-quality fuel, o r even carbon buildup in the engine.

To fix these issues, regular maintenance, using high-quality fuel, ensuring proper oil levels, and addressing any engine wear early on are key. If the noise persists, it’s best to consult a mechanic to inspect the engine for internal damage.

Have you encountered any knocking o r ticking sounds, and if so, what did you find to be the cause? How did you address it?
