    Flooded engine

    Hi folks, bought a 2018 320i x drive with 17k. It had some water ingestion and I had a few questions I was hoping to get some feedback on.
    I drained oil twice and emptied the intercooler. Oil was milky but there was not a defined oil and water seperation.It runs, has misfire on cylinder 1. Idles rough but runs smooth at 3k rpm. I was thinking bent rod but it wouldn't run well at high rpm if that was true. I'm going to replace plugs this week, thinking maybe a fouled one.

    If I do have to replace engine do these come out from the top or drop subframe. I have a lift in my shop.

    Any info appreciated.

    Surprised by the lack of comments on this forum. Anyway, new plugs and the car runs perfect. Looks like it sucked in enough water to stall out and foul the plugs. I bore scoped the cylinders and they look fine.
