Link doesn't work bud. Being a forged build, is it maybe piston slap? A gentle knocking that goes once the engine warms up etc?

Does sound like a little knock but every bottom end that I have heard sounds a lot worse and progressively louder when you rev yours seems to be doing it only on very slight rpm your better waiting for a engine guru to come along.

Apart from the PAS whine, the 'clacking' noise when you bring the throttle on sounds abnormal - have it checked out asap.

It's very hard to tell from videos as engines sound terrible even when they're not. I'd hazard a guess at the bottom end knocking going by what car it is and the sound.

Does sound like big end knock. But not conclusive . How many miles since the build?

First instinct was to say valve head but that would cause a drop in compression but shape looks too odd for a valve head, has the engine been tested for compression and leak down?
