Anyone have stock one owner 1.3 Sami that when the engine warms up you can hear a loud knock around cylinder 3-4, or when you accelerate the knocking gets worse? Some say its rod bearings or valve lash or rocker arm adjustments? any input? Thanks
 
They're also bad for piston slap. I couldn't start to diagnose without hearing it in person, though. Have you adjusted the valves? They usually tick rather than knock, but could be contributing.

This is a knock, if you rev the ewngine you can hear it kick in. Not familiar with piston slap.
 
If you can borrow one, get one of those automotive steathascopes (spelling?). Run the motor and move the scope thing around until you can pretty much pin point it. Then go from there.
