How to Prevent Engine Knock On Startup that Goes Away?Įngine noise can be caused due to engine piston slap or wear and tear of engine parts. To prevent that from happening, you should follow the guide below and use performance-enhancing engine oil treatment additives like this one– However, it’s a sign that there are some issues inside the engine which may deteriorate soon. If engine knock on startup goes away after a few minutes of warming up, it’s most often nothing to be worried about particularly if you hear the noise only once in a while and don’t feel any other problems with your vehicle such as engine oil leakage or engine overheating. If engine oil is reaching the engine parts in wrong quantities, or if the car is old, it can cause carbon build-up over time which will lead to engine knocking or engine piston slap while turning on your vehicle. If these bearings become worn out due to wear or tear, it can lead to piston slap or even knocking on engine startup. Worn-out bearingīearings are rotating engine components that allow smooth movement of the engine parts in the engine block. The best solution for this problem would be changing your vehicle’s engine oil regularly, working with an engine oil additive to protect engine parts, and getting your engine checked at regular intervals. It may cause piston slap or even engine knock on startup as well.
If engine oil is not reaching the engine parts properly, it can lead to sticky engine lifter and worn-out engine seals. If it does go away, we still recommend you to be cautious and have it checked up so that it lasts long. It’s high time that you take your car for immediate service if you hear any unusual or weird engine noise that doesn’t go away after a few minutes. Most often, it happens due to worn-out engine rings and/or engine bearings which let metal particles flow into the engine oil, leading to the formation of sludge in the engine. Worn engine parts can be another reason for engine knock noise on startup. Although not a big problem yet, but piston slaps happen due to either bad timing of spark plugs or worn-out pistons. Once you start your vehicle and let it heat up for a few minutes, then there’s very little chance of engine piston slap. Piston knock can be caused due to engine piston moving from side-to-side during engine rotation, as it tends to move around more when cold.
