I just bought 82 FJ 60 . It’s bone stock . It runs pretty good . It has a small exhaust manifold leak and the gasket for the EGR valve is pretty much gone . It does ping when going over a bridge or over pass . I know this subject has been beat to death . I’m seriously considering desmogging it. I’m looking for guys with actual experience doing this . I read over the info on this site a couple times. Some of the pics are hard to make out . Any help or recommendations will be greatly appreciated.
