I ran engine cleaner before i changed oil just few hundred kilometers ago.
Today cold start and it ran nice. After it warmed up and drove few kilometers one lifter is ticking. I ordered oil pressure gauge, so let's check it. I found bmw bulleting about air getting into oil stream or oil pump check valve not working properly. So probably gotta take the oil pan out and inspect the pump.
And when I got new lifters in I drove it like I stole it.
