How long does it take for a piston slap to go away?
So far the piston slap is nearly gone. From startup, I get 3, maybe 4 taps before it completely subsides, vs the 10-20, sometimes 30 seconds of noise. When I immediately begin driving it after start up, I used to get tapping at lower rpms, (1200-1800). Those are now gone, even with a completely cold block.
