I am interested in whats considered OK, the chirping is loudishThere are a couple of bulletins out relating to noise on L77's in VF1. One relates to a chirpy type resonance noise and the other is that a small amount of piston slap is within engineering specs (tolerances of piston to bore are designed to be correct when warm/at operating temperature).
You probably need the second opinion, but LS motors are noisy. They've been that way for the ~18 years they've been in Commodores and it isn't going to change. If it's not clattering or badly chirping from the valvetrain and it's not loudly knocking from the bottom end it's fine.
Happy to have a look if you're ever inland a bit from Bris.
I do work in Toowoomba and Warwick
Where are you located?
