Exclamation Suggestion 07 328xi

I need ideas on what to do next I'm getting this ticking/knocking sound when engine is warmed up. At cold start engine sounds perfect I changed all Hydraulic valves, flushed out engine with diesel, changed oil went from 5w-30 to 0w-30 and back to 5w-30 it didn't do anything, I bought all new spark plugs didn't do one thing, I checked rod bearings it had some scratches around the bearing shells but it looks normal. Don't know what to do now, any suggestions of what could cause this problem?

This is what it sounds like
