“Knocking Sound from the Engine — Is It Rod Knock o r Something Else?” Detail:

I’ve been hearing a deep knocking o r tapping sound from the engine of my 2015 Jeep Cherokee, especially on startup and under load accelerating uphill o r with passengers. The noise seems louder when the engine is cold. Oil level is okay, and I use synthetic oil. Is this likely to be rod knock, lifter issue, o r timing chain related? What are common causes in Pakistani climate/road conditions, and how risky is it if left untreated?

A knocking sound from your Jeep Cherokee’s engine, especially during startup o r under load, can be concerning and is not uncommon in Pakistan. This noise could be due to worn engine bearings commonly known as rod knock, faulty hydraulic lifters, o r issues with the timing chain system. In Pakistan’s hot climate and dusty driving conditions, if engine oil isn’t changed regularly o r the wrong oil type is used, internal engine components wear out faster. Many owners also report similar sounds caused by carbon buildup o r poor fuel quality. Its critical not to ignore this, as actual rod knock can lead to complete engine failure if untreated. A mechanic should perform a compression test and oil pressure check to confirm the exact cause. Regular use of quality synthetic oil and timely maintenance can help prevent such engine wear in the future.
