DROD---sort of fixed it but not really. So, a few months ago, i took it in to a local 4x4 shop (same guy has done other work for me--disc brake conversion/4x4 issues, etc) He basically did some top-end maintenance stuff. New gaskets,seals, etc etc. Well, I didn notice that the exhaust smell wasnt as bad as before, but its still there. However, with my exhaust running straight out the back-end, I've heard that could be adding to the problem as the exhaust balls up behind the tailgate. So, Im gonna get my pipes turned to exhaust out 90degrees behind the wheels and see if that works.
