So picked up a truck with a blown head. Coolant is visible in the oil and radiator level is not visible from cap. I Won’t be able to start ripping apart for a couple weeks. Question is should I drain oil or leave it sealed up until I can pull the motor? Don’t want the cylinders to rust by introducing oxygen Or is my thinking incorrect? Picture is hard to see buts it’s chocolate milk for sure!!
