Started as an oil cooler gasket leak. Fixed. Than a cylinder with no contribution at idle. Cylinder 3. Injector 3 had a clear mechanical failure (screw at top came undone, had to fish out the nut with a magnet). Replaced the injector started it back up, had to replace the injector harness. New one was garbage, put the old harness back on, all injectors passed buzz test. Started it up after reinstall and the knocking started after running for probably 30 seconds. Originally the knocking was very consistent. Second start up for the video knockings reduced.
