    I'm still waiting for the new UIM, but since there's plenty to do before it arrives, I've started. I took a few photos and will post them. This shows what everything looked like. So far only the intake filter cover and hose removed and a few of the connectors off the throttle body.

    From the front of the engine, obvious signs of leaking.

    A bit of oil puddled in the LIM

    The good news, no water/oil "milk shake".

    Here, you can see the evidence of the gasket failure. The space between the EGR pipe and the water port is destroyed.



    Confirmed here. The gasket on the UIM

    I question if this is a "distorted" or "warped" plastic UIM failure. It might just be a simple failure of the gasket. Opinions?
