Diesel\'s Smog Exempt in CA? My boss was telling me that if you buy any diesel truck or blazer they don't have to be smogged. So basically what he was saying is you could get a diesel blazer... Drive it till the engine goes, or just rip it out and replace it with any enigne you want. Like a "no way it's smog legal" 383 or 454 you've always wanted. And as long as you don't get pulled over for it then you'll never have to be smogged because they'll think it's a diesel since it originally came with it. ? Sound like it could work?
