Thread: Cracked exhaust manifold

  1. #1

    Default Cracked exhaust manifold

    Thought I had another exhaust leak, caused by air brake backpressure. This time, it turned out to be the driver's side exhaust manifold - developed a crack.

    Was out of town, and didn't have time to weigh the options of the aftermarket replacement peice.

    Bill from GM shop, parts and labor is $833 + tax.

    The BD replacement manifold is less than $300, and is absent the "dent" (for the driver side). Takes about an hour to replace (or any shop can handle it, for a LOT less than the dealer). Simple. Not sure about the 4500. Is access better, or worse, compared to the pickups?
