yes at this rate it does sound more like a valve seal problem than a ring leak, which is a very easy fix.... it'll take you a couple hours to a full day depending on ability, but it probably will be your fix... its very cheap to do, cheaper than head gaskets.... and yes i agree the lucas additives do work well, but one you start burning oil an additive wont close it enough to pass a smog inspection.... i'm suprised arizona has a cutoff earlier than cali on years.... everything 74 and below is smog exempt here
