engine knocking/rattle noise (video) what is it

hi guys,

do you think this is the bottom end or the variator? i have some people telling me its the bottom end others variator, in person it does sound like the coming from the top end, but obviously i cant be sure.

on idle it knocks, when reved, it turns into a rattle, which sounds very 'loose' and like something is rattling about

A variator sounds like a diesel. It is normally on start up for about 5 seconds. Mine now rattles longer than that but it's been there for awhile.

Mine made similar sound when balance belt tensioner went and released the belt which luckily did not get caught in timing belt. If this engine is 2 litre TS it is worth taking timing cover off and checking the condition of the belts. If something is rattling there it should be obvious.

Its not a variator
As Visconti said, take the cover off, check the belts. If the sound comes from the engine itself (rather than under the belt cover) you are need to prepare for the worst..
You could hope its only the tappets (does not sound severe enough for a bottom end) but who knows.

That noise sounds like bottom end knock to me.

you'll find one of the shells has turned on the crank, same as it did on mine.
