How to completely get water out of oil
Hey fellow Cherokee OR Jeep owners I have a issue that I'm kind of stumped on .
I went wheeling got stuck in a pond this past labor day weekend went in to fast and got a little water into my intake manifold and air filter got soaked.
So I got a little water in the oil noticed it when we brought my jeep back to camp changed to the oil twice since then and its really almost gone but a hair line amount of milkness at the very bottom of my dipstick but you can only notice it if you let the jeep sit over a period of time on the dip stick
Is this somthing I should be worried about?is it a huge deal ? should I just drive it a little bit longer for 1k miles ? Their is no change in engine noise or performance. Any input would be awesome thanks !
Vehicle Info
-88 Cherokee
-4.0 Liter

you drain all the oil, run a quart or two through with the plug still out, then fill it back up. Yes, you want all the water out or it'll get to your bearings.

i heard that you drain everything filter and all
fill it with 5-6 quarts of cheap oil
start and idle for a few min
drain again
refill
change oil after 1k miles again
oil is cheap compared to the cost of what water will do inside

I hydrolocked one of my old cars going through a parking lot that didn't look quite as flooded as it actually was.
Drained oil, shot the cylinders with WD40 and cranked it to get the water out of the cylinders (spent about 10 minutes repeating this process to ensure it was all gone), took apart the air cleaner box and cleaned/dried it out, topped off the oil, ran it for a half an hour, changed the oil and filter again, then drove it for about 500 miles and changed it again.
No problems after that other than a bad throttle position sensor.

I would change it one more time andrew, put your jeep on ramps or something over night draining, change your oil filter, refill and you should be good to go.

The "somehow" is called hygroscopy. Most of the time water in the motor because of condensation, it's nothing to worry about for short periods of down time. Most of your engine is sealed off to the environment and can't collect enough water to cause a condition. IF the motor were to sit for an extended amount of time then the water could cause damage.
Yes, some of the water will evaporate but if there is too much then the damage could happen before it leaves the motor in vapor form.
I would take the other suggestions of getting the water out.
I hope that makes sense...

Doesn't sound like you need to be worrying. Take the Jeep for a nice long drive to get the oil heated up. Provided your CCV system is operating correctly (is it?) that water will disappear.

A lot of people - including parts stores! - incorrectly call this PCV (Positive Crankcase Ventilation). The difference is a valve is present in a PCV system where our CCV has a metered orifice allowing for flow all the time. Even though CCV is more open compared to PCV, its quite closed compared to the draft tubes it replaced
