The vector analyzing power (iT11) in elastic π-dpol scattering has been measured for several angles at Tπ=219, 256, 275, and 294 MeV. Strong oscillations are confirmed at 256 MeV. The data are compared with Faddeev calculations, alone and in combination with either of two resonances. At 219 MeV the Faddeev calculations are consistent with the data, while at the higher energies the general trend of the data favors the admixing of the 1G4 dibaryon resonance. The forward-angle data at 294 MeV are not well described by any existing calculation.
