I don't think that noise is from the WP. My thought is that something Mechanically changed between the crank position sensor and the cam position sensor after AOS failure. Possibly from hydrolock, but first thing you need to confirm is mechanical integrity. Since the CPS gets signal from the flywheel which is bolted to the crank it is pretty safe to assume that didn't change. The mechanical relationship between cams and crank is maintained by cam chains and their tensioners. The cams could have slipped at their adjuster plates or the cam chain tensioner and/or ramp could have failed. Either one of those scenarios would cause the cams to be retarded. However with the noise from the engine, cam chain slop is more likely. Both of these can be visually confirmed or eliminated by checking the cam timing.
