My 79 El Camino's dip stick tube broke off due to rust, and to make things worse we've had rain here in Austin these past couple days so I suspect there's gonna be water in the oil pan as well. I'm new to this but I'm not a ****ing idiot (not completely at least) and haven't ran it so I imagine the water is relegated to the pan. What's the best way to flush out the water? I understand an oil change and filter change will be necessary but I'm unsure as how to remove the water while making sure there's actually no water. If I kill the motor in this car I'm actually going to cry.
