Piston slap, #4 cylinder only. Cylinders 1, 2 and 3 are worn almost
none, but #4 measured .006 oversize. I rebuilt it with std size
pistons, assuming that they were worn more than the bores, and were
the source of the tonk - tonk piston slap noise.
Didn't work. It's still there. Compression is good, 155-160 psi.
Doesn't smoke or use any oil.
Goes away when fully warmed up, but...
Questions -
1) Is this anything to lose sleep over?
2) Any "tricks" to lessen the noise?...uh, rebore and new pistons
doesn't qualify as a "trick".
