What was replaced on the rebuild?

On-the-bog

By bearings to you mean the crank bearings?

on a 2.5 HG is a full rebuild including bottom end or there is a high chance the crank bearings will fail. I suspect that's whats happened

Faulty cambelt tensioner / pulley ?

Might sound a bit of a strange suggestion, but if you do a search in youtube you'll soon see it's not uncommon ie:

This guy's RS developed a knock after the head gaskets were placed and a new timing belt tensioner fitted.
