You ignored the best advice.

A turbo will still make boost just fine with a busted ringland, there is almost no correlation for the 2 in that sense. An AOS does nothing for knock. AOS will get rid of the oil in your blow by, not reduce knocking.

Best thing you can do is a compression and leak down test.
