Tap for 5-10 second pretty normal. Rattle is tensioner related.
Tap on cold start is usually cam followers filling up and it's fairly harmless at idle to tap the cam.
Share a recording.
Loose tensioner is the main cause of chain guide failure on M62. They can go 300-400,000 miles if you change the tensioner often enough. If you can't confirm I'd change with OEM tensioner
