Imagine you are on a long drive with your family, and driving your BMW on the highways gives you immense pleasure. But suddenly, you notice a clicking or ticking noise from inside your hood. The situation will suddenly convert to an alarming one in no time. Whether the noise occurs at idle, during acceleration, or after a cold start, it may be indicating anything from low oil levels to more serious mechanical issues. It might be tempting to ignore it, but this sound can indicate problems that need attention. It’s essential not to ignore these noises, as they can indicate minor issues or developing problems that could lead to severe engine damage if left unaddressed.
At Solo Motorsports, located near you in Duluth, GA, our German automotive experts are here to help decode these sounds and keep your BMW running smoothly. In this blog, we will break down the common causes of engine ticking in BMWs, what it could mean for your vehicle’s performance, and when to bring it in for professional inspection.
Understanding the Ticking Noise in Your BMW
A ticking noise in a BMW engine often indicates issues related to valvetrain components, low-level oil levels, or worn engine parts. While some ticking can be harmless, persistent or loud ticking should not be ignored. Addressing such issues under the supervision of expert, certified technicians like those at Solo Motorsports, located near you in Duluth, GA, can prevent more expensive BMW repair work down the line.
Low or Dirty Engine Oil
Low or dirty engine oil is a frequent cause of ticking sounds in BMW engines. These engines depend on clean oil to lubricate parts and maintain hydraulic pressure in the valvetrain. When oil becomes contaminated or runs low, vital components of the engine, like the hydraulic litters, may tick. This issue often presents as a noise at startup, increased engine temperature, and delayed oil change intervals. BMW engines rely on proper lubrication, and if the oil level is low or contaminated, moving parts may not be adequately lubricated. Metal parts rubbing against one another can result from a lack of lubrication, producing ticking sounds. Frequent oil changes using good-quality oil prevent this. If you face such difficulties, you may visit any of our garages located near you in Duluth, GA, for a regular inspection.
Faulty Hydraulic Valve Lifters
Worn or clogged valve lifters can cause ticking noises, especially in older BMW models. Lifters are designed to maintain the correct spacing in the valvetrain, and failure can result in tapping sounds. These HVAs are the components that control the intake and exhaust valves, making the engines run smoothly. When they fail due to wear or oil pressure failure, they produce a ticking sound. These issues are common in the N52 and N54 engines, as well as in the BMW 3 Series and 5 Series. There is no alternative option other than replacing the lifters to eliminate and resolve this problem. Proper oil maintenance and replacement of the lifter, if necessary, can address the noise and eliminate it. You can drive into our garage located near you in Duluth, GA, for a proper inspection.
Loose or Faulty Spark Plugs
Sometimes, a ticking sound can be caused by a simple issue, such as a loose spark plug. If a plug isn’t fully sealed or if the threads of the plug have become worn, combustion gases can escape and create a ticking and popping sound that mimics internal engine issues. This noise typically originates from one side of the engine and may become louder under load. In more serious cases, the plug may black out entirely or cause misfires in a cylinder, especially if the ignition coil is also affected. Drive into our garage, located near you in Duluth, GA, where we inspect the spark plugs for signs of wear and damage, and ensure they are correctly tightened. We also replace them with the new ones using OEM parts, if needed.
