It is possible that this noise could be coming from a faulty pulley or bearing in your engine. It is important to have this checked and replaced if necessary, as ignoring it could lead to further damage and more costly repairs in the future.

I had a similar issue with my M4 and it turned out to be a worn-out valve in the engine. I would suggest taking it to a trusted mechanic to have it properly diagnosed and repaired.

Make sure to check the engine oil level and quality, as low or dirty oil can also cause strange noises in the engine. If the oil level and quality are good, then it could be an issue with the timing chain or tensioner.
