    Hello all,
    When I start my '89 Blazer 350TBI, the exhaust is quite visible (common in Michigan winters). But from my experiences, the exhaust usually disappears after the engine is warmed up. I can drive my Blazer for a while (definately warmed up) and still see significant exhaust. I don't think it's oil, as it doesn't look bluish/white or leave a trail when driving. Also my oil level and coolant levels stay pretty constant between oil changes. If it matters, I have dual exhaust.

    Maybe I'm just paranoid, but these things get to me. Any information would be appreciated. Thanks.

    I wouldn't worry too much how excessive exhaust fumes. I know when it is real cold out everyones exhaust is more noticable. If it doesn't smell like burnt oil or gassing I wouldn't worry.

    BTW, I from Michigan also. I live in Ann Arbor, where are you from?

    Yes, I have noticed this also. I think I notice it more when the air temperature is low while the moisture content is high.

    I would agree with the other poster, don't worry about it, it is just water vapor from your engines combustion cycle.

    PS. I work in Ann Arbor, look for me while your driving, white 1990 Silverado K5 with Maroon graphics.
