While working on my truck today I noticed the tag on the passenger side valve cover said: "engine is certified for sale in California in new vehicles rated above 14,000 GVWR, engine is OBD II exempt." So does this mean I have a California truck or do all 7.3s tag say that. Plus what does OBD II exempt mean? Also any links on diffenances between California and normal trucks.
