Maintenance/Repairs

Hey my Volvo v40 T4 2003 started making pinging sounds on cold start and while warming up if I rev it
It follows rpm
Before it started I noticed my plugs were white with a little deposit on them all 4. Ran great and still runs good making about 1 bar boost.
This sound freaks me out a bit
