My son and I are trying to learn but need a little help and guidance. Purchase a nice YJ almost four months ago. Had a “friend”machanic offer to get it emissions ready, long story short he blow rods through our 258. Our YJ originally has 2.4. Not sure if the mayyets. Now I am trying to find a new engine and learn the terminology asI can afford to get taken again. My son is really trying to learn and work through some of the wiring but wete to begin engine wise people want up to $5000 to do it. That can’t be our only option.
