Question about 1996 BMW 318
We just replaced the hydraulic lifters and timing chain tensioner to fix this problem. However, it didnt make a difference.
1993 M42 153,000 miles. Car sat for two years with out being started. I have changed the oil 3 times in 5'000 miles that I have driven it. The noise is getting worse the more I drive it. The engine does fine when cold, but noisy after it is ran for a few minutes, especially, after driving over 3,000 rpms(highway) for any period of time.
Listen to the video, engine cold and engine hot.
Could be the oil pump. Had the same problem w/ E 30. Installed a pressure gauge and check performance at different speeds. Pressure was consistently low against specs. Change the pump . . problem gone.

To anyone experiencing this noise, even to a smaller degree. Look Into getting your Timing chain replaced, along with the timing chain tensioner and timing chain guides. The M42B18 Engine always makes it known to its owner when the timing components are due for replacement, unfortunately to the tune of a Very loud engine. Though only of course because of lack of timing chain tension causing slack.
In this current situation, I'd advise having the timing components inspected and Replaced by a mechanic ASAP, as the engine sound is loud enough to warrant thoughts of possible engine failure in the very near future if not inspected.

Is your problem has been solved? because I have quite the same noise (maybe a bit less) on the same car.
