I am getting intermittent signs of water in the oil on the dipstick. When I have drained the oil there is zero signs of contamination.
I usually drive my jeep for about 45minutes to an hour at a time. Gets up to temp as expected. Whatever signs of moisture will be minimal on the dipstick, around that washer-like centering tab brazed onto the stick. I check the stick often and do not always find moisture traces. Oil level remains consistent. Is this condensation or do I need to jump into the bigger picture? I will get a photo this afternoon.

Probably just condensation. As you know, when that PCV hose was crimped, the PCV system was pretty much inoperable. Now that you’ve got the system working, it should clear up, but it may take a while.
Wet weather and running through water don’t help. 😁😉 BW

Here are pictures. This is the worst it has been but I had just made 4 water crossings 24" deep. Slow and easy but the fan still puts water up on the battery., oil filter canister and air filter. I checked the air filter and I do not think any was pulled through the element. There was a little white in the oil filter canister the rest is on the stick and in the stick tube.

That's the same look on mine when I had no PCV and no gasket on that cap (but much worse). Make it air-tight so the PCV can do its job and it will disappear.

Just a thought. Is the bottom of the dipstick tube sealed where it press fits into the block? I believe they can work loose over time. Good luck!

And a very good thought Ron. Especially with a negative pressure crankcase.

I didn't measure, but fording 2 feet of water might submerge that joint. Nothing a good cleaning and some silicone caulk wouldn't fix. Maybe a little pipe expanding tool action if need be.

Keep in mind, your submerging a hot engine in cold water, seals are made to keep oil in the engine, rapidly cooling it may pull water through the rear seal/front seal. I went through a creek years back in South Dakota and water ran through the Jeep doors, I too had water vapor much like in the topic of this tread.

Interesting information. I think Ron hit on something, as my jeeps dipstick tube is, shall we say, less than secure. I will check the connection and seal it. I am also going to check the rest of the systems tubing for obstructions. I know the PCV valve works, but I never checked the tubes the system relies on.
But I think its water infiltration, as this has not been evident except when I am fording. Thanks to all who responded. |

Lee has a good point, and with the PCV inlet hose kinked off, air cannot enter the crankcase to replace what’s pulled out by the PCV valve action. This means low pressure (vacuum) in the crankcase so air and water will enter anywhere they can.
I have a Snap-On socket (don’t know the size offhand) that I drive into the lower end of the fill pipe to expand it to just the right size, a nice tight fit. Please repair it correctly - don’t gob it up with a bunch of silicone. BW

Name dropper. Would a Craftsman socket work too?

If it has the right outside diameter. And really, I’d rather hammer on a Craftsman if I had one.
BW ETA: I use a Craftsman extension so I don’t have to hammer on my Snap-On tools.
