    Blue smoke on startup is normally caused by leaking valve stem seals.

    However, I've not heard of any real valve stem seal issues on LS motors, and your car only has 78K on it.

    Firs thing I would check is the PCV system. Ensure that its functioning properly and isn't plugged up or disconnected.

    What kind of oil do you run?? Its also possible that the oil drain holes in the head are plugged with sludge, causing excessive oil to be left in the head and letting it drain down the valve stems.

    Usually valve stem seals. Guides could be wearing also, but that is less common.

    No prob. If the PCV looks clean and functions properly, you might want to pull a valve cover and inspect the cleanliness of the head. If you see gunked up oil everywhere, or pools of oil that aren't draining through the drainback holes, you've at least found part of your problem.
