The gluon polarization functional is evaluated for a generic linear covariant gauge and for any space dimension in pure Yang-Mills SU(N) theory up to second order in a generalized perturbation theory, where the zeroth order action is freely chosen and can be determined by some variational method. Some numerical data are given for the gluon propagator in the Landau gauge and compared with the Feynman gauge. A comparison is given for several variational methods that can be set up by the knowledge of the second order polarization.
