Engine knocking o r ticking is often linked to poor fuel quality, which is common in parts of Pakistan where low-octane o r adulterated fuel is sold. This can cause pre-detonation knocking in the combustion chamber. Ticking noises could also come from low engine oil levels, worn valve lifters, o r carbon buildup. Using high-quality fuel, regular oil changes, and occasional engine decarbonization can help. Persistent knocking should be checked by a mechanic, as it may damage engine components if ignored.
