  The CP conserved non leptonic $K\to \pi \pi \pi$ decays are discussed within
the chiral quark model, including chiral perturbation theory corrections. All
amplitudes are parameterized in terms of quark and gluon condensate and the
constituent quark mass. The same values for these parameters that can be
obtained by a fit of the $\Delta I = 1/2$ rule in $K\to 2 \pi$ give a
reasonably good fit in the $K\to 3 \pi$ case. We compare with the work of other
groups.
