Help N52 ticking/thumping on angle https://www.e90post.com/forums/showthread.php?t=1590960

Thats one of the joys of owning this engine across all of the BMW cars from this era. It is considered as normal noise and there is pretty much nothing you can do about it. It does not matter if you change oils, viscosity of oils, drive short/long commute, replace lifters etc. Just have to live with it I assume thats the same N52B25 than I have?

My car ticks 100% of the time during winter until the engine is at around ~80deg oil temperature. In summer its much more rare. Also some guys have greatly reduced the noise by removing the last o-ring from the oil filter stick. The reason why it works is unknown but they have tested that well over 25k kms and it works.
