Hi guys
Last week I bought a 2006 BMW 330i (N52). Got it home and changed the oil. Noticed that it was behaving weirdly, different from my previous euro cars. Kind of stumped as to what is going on in the engine. I also changed the oil again after a short time (150 miles or so) and the behavior is about the same. Attached are videos of what is going on. Found no metal in either engine oil filter. Engine runs smooth with no alarming noises. Occasional ticking on cold starts, seems as though the N52 suffers from lifter failure. Once warm the engine is always free of noises. The history I received with the car suggests that oil changes were regular at about every 10k miles. The videos show the 'latte art' behavior. The oil fill this round was Liqui Moly Leichtlauf High Tech 5w40. Looking for any possible explanation for the behavior, or if I'm just being paranoid.
