    What should I do?

    My 454 is finally sitting on the Blazer, but I still hadn't had time to install the intake manifold and timing cover. I had a huge plastic on top of the whole front end of the Blazer.

    Well today we got some rain, and guess what, the plastic was not covering everything well, so a good amount of water went into the 454!![​IMG]. At least the oil pan drain plug was not installed, but when I cleaned the oil pan before installing it I realized that a good amount of water could remain in there. As you can see, I'm pissed.

    Should I remove the pan (wait 2 weeks for new gaskets) to clean it from all the water, or can I just close everything up, add the 2 gallons of oil it takes and hope all the water evaporates?

    Your words of confort are welcome.

    Pull the plugs and crank the motor over to empty the cylinders...with no manifold on the ports to the cylinders are open too. Squirt a little oil into each cylinder that had water come out and spin the motor over a bit. Use some compressed air to dry what you can see and add a quart or two of oil. Let it sit for a day or so and drain...the oil will float on top of the remaining water so the water should drain first. It will just need a little time for the water and oil to separate...

    You dont need to remove the pan. Just do what trusty says. Then get that motor up and running ASAP. Now that there is some water in it, rust is an issue. Get it running and good and warmed up. The little water remaining in the engine will be emulsified in the oil. Then change your oil just to be safe and everything should be fine.

    Do what the other folks suggested and add a quart of kerosene. Run the motor for 10-15 minutes and drain. The kerosene does a really good job of displacing the water into the oil. I did this on a lot of shop cars that people drove with the temp gauge pegged and blew head gaskets etc.
