When I bought my Euro, it had the same tappet noise. The service history indicated that a Synthetic Valvoline 10-30 oil was used. I changed it a week later with my favourite oil BP Visco 5000 5W-40. And the tappet noise dissappeared. Worked for me so give it a go...

So is it tappet or injector noise, guys? lol. Make up your minds...
