Re: Sudden big end noise?

You need to be sure where the noise is coming from - top or bottom of the engine as other replies have said. A stuck valve can make you think you've got bottom end knocks as you get piston to valve noise and cam follower noise as a result. The fact it's only firing on three is suspicious but could be a red herring of course.
