I recently noticed a strange ticking noise coming from the engine of my BMW 3 Series. It seems to be happening more frequently, especially when the engine is cold. What could be causing this and should I be concerned?
ReplyThe most likely cause for the ticking noise is a faulty hydraulic lifter. This is a common issue with BMW engines, especially as they age. It's important to have this fixed as soon as possible as it could lead to further engine damage.
Another possible cause for the ticking noise could be a loose valve or rocker arm. This could also be a result of wear and tear on the engine over time. It's best to have a professional mechanic check and adjust the valves if needed.
