Variator or big end?

Late August I posted a video link to my wife's 147 2.0TS complete with orrible engine noise, and the general opinion seemed to be big-end (as was a local non-alfa garage)

It's been languishing SORNed in the garage ever since, but we recently put it on ebay for spares or repair.

However a helpful chap has popped up there stating that the noise is definitaly a failed variator, and he has saved many an Alfa from the scap yard for the sake of a relatively easy and inexpensive fix. (not offering to fix it, just being helpfull)

So here is the link again, and anyone care to express an opinion on the variator issue?

I've not watched the video. But a failed variator is a diesel rattle.
A big end is a knock.

This is big end knock on my own car.

Yep, Mr gbzrope, that's 100% not the variator on your car, in fact its such a painful noise to listen to I couldn't manage the whole video!

I personally don't know what a failed variator sounds like but i do know what failed big ends sound like, and i'm sorry to say GBZ, your's does sound like big ends to me.
Whilst the bearings themselves are not too expensive, and on some cars you can get to them without taking the engine out, if the crank is marked, then it is an expensive job.

Sorry but its big end bearings, big chance is that your car has suffered a cam belt failure, this causes shock in the big ends. The big end bearings should have been replaced with the engine rebuild as the problem wont be evident till after thousands of miles.
