Hi .
This is a typical valve train rattle ,the hydraulic valve are not fully clean .
The best way to sort this issue out is to do a 20 minute oil flush.
Add one can of engine oil flush to engine oil .
Start engine and let idle for 15 - 20 minutes .
Switch off and drain engine oil .
Replace oil filter with an original filter .
Fill with new good oil like castrol etc..
The flush cleans the small bores in the hydro lifters .
If this does not work replace the lifters ,but to 90% if the tapping goes when engine is warm they will clear with the flush .
Need further assistance with this issue then please get back to me with the reply box below if needed.
Kind regards Greg
