2002 BMW 330i Engine rattle/ticking [Video included]

Hey fanatics!

Long time lurker and reader, but I haven't posted much.

I'm having an engine sound issue with my beloved 330i.

Long story short, after initial start-up there is a persistent rattle or clicking sound coming from the engine. It appears to come on once the car has sufficiently warmed up.

I've had the car for a little over a year now and have been trying to diagnose the problem as best as I could. I'm not sure what kind of oil the previous owner has been putting in, but I just replaced the VANOS seals and rattle rings (kit from BeisanSystems) and at the same time I did an oil change. I put Royal Purple 5W-30 (please don't flame me for not using BMW certified LL-01 oil ;P) into the engine, as I had a bunch of it laying around from before so I figured it would be okay to use in the bimmer. End result is still the same though. I have also tried unplugging the DISA unit as some posters have suggested, but that didn't appear to help.

I've uploaded a video onto YouTube so you guys can get a better idea of the issue:

I'd greatly appreciate any input and help from you guys, thanks!

Still have the problem since October? I suggest you buy a mechanics stethescope and try to pin point the source of the noise. My first guess would be a lifter or injector, but it could be a number of things. Does it go away when you rev the engine?

Thanks for the suggestion; I will take it to my brothers shop and see if he can find the location of the noise as he probably has a stethoscope.

Ya, it goes away once you rev the engine and then comes back during idle.

Hi there, I'm new to the forum and came across this post. I have the exact same noise (I can't find a video that matches the noise as perfectly as the one above does), and was wandering if you found out what the noise was and how to fix it. I'm hoping someone here knows what it is and how to fix it. Thanks in advance
