Here's the kicker with the oil flush FFDP suggests. This is only if you get water in the oil. I do the job careful to not get any water in the motor. Then I fire it up for a minute and then change the oil.
Reason #1 The steel oil pan most have on their motors (95-03) have about 3/8 of space below the drain plug. With water being heavier than oil, if you dropped a bit in there, it would be sitting in the bottom of the pan. Since I don't get much if any in there..it's not an issue.
If you got a decent amount in though..then you absolutely want to drain it all off. Also once you are up and running, watch the oil for signs of milkiness. Change the oil until it's no longer milky.
