We consider the so-called "eV seesaw" scenario, with right-handed Majorana mass MR at eV order, extended to four lepton generations. The fourth generation gives a heavy pseudo-Dirac neutral lepton, which largely decouples from other generations and is relatively stable. The framework naturally gives three active and three sterile neutrinos. We update a previous numerical analysis of a 3+3 study of the LSND anomaly, taking into account the more recent results from the MiniBooNE experiment. In particular, we study the implications for the third mixing angle sin 2 θ13, as well as CP violation. We find that current data do not seriously constrain more than one sterile neutrinos.
