[en] We test the recent proposal of using the Ward identities to compute the K0 - K-bar0 mixing amplitude with Wilson fermions, without the problem of spurious lattice subtractions. From our simulations, we observe no difference between results obtained with and without subtractions. From the standard study of the complete set of ΔS = 2 operators, we quote the following (preliminary) results: BMS-barK (2 GeV) = 0.70(10), < O7>(I=2)K→ππ = 0.10(2)(1)GeV3, < O8>(I=2)K→ππ = 0.49(6)(0)GeV3
