My 1970 Scout 800a is giving me a little trouble. Runs great, starts up, idles, makes head turning good noise! BUT I am getting blow by through my dip stick. I have checked my PCV valve (not sure what Im looking for there), new hose, new breather on the other cover. Not sure what else to do. I don't want to believe it is bad rings, does anyone else have this problem or a fix?
