Yeah, post #7 is about my issue.
I took the VANOS cap out through the oil filling hole at June 4th. It was already off VANOS unit, broken and rotating inside and making noise during cold start since September 2017. And after I took out broken cap I didnt hear this noise anymore.
Both caps on bank #1 are gone at pieces and fell down in the oil pan.
last week I took off VANOS caps from bank #2.
