Hello everyone. I noticed weird chunking sound in engine (dd15) 2014 has 865000 miles on it. First I noticed decreased oil pressure since last service done which was 3000 miles ago. But there is no engine check light on. Today I noticed this weird sound. Please help what it could be.
Thanks in advance. Please see this link

If it were a gas burner engine I’d say it sounds like a backfire through the egr.
