There was no water in the oil, just in the fill tube. It is a daily vechicle driven well. The moisture was just after 7min. for the flush to work.

it has to do with the plastic and the fact that the cap is so far from the engine. Heat will go to the nearest place to escape and when it does it will build up condensation. It is not an engine problem but is a engineering problem. GM and Ford normally put the oil fill cap right on the valve cover so there is not much area for the heat to escape. Dodge for some reason decided to put the long neck on the 4.7 and the 3.7 in the jeep liberty. They both will build up moisture. It is nothing to worry about it has nothing to do with the in side of the engine. It is just in the fill tube and cap. Just take the cap off every now and then and clean it out so it doesnt get built up too bad. They did start puting a baffle in the fill tubes on those applications. But that really doesnt do much. But any way dont worry about the engine every one of these engines does this and I see it as being normal now. When I first starting seeing this I thouhgt there was a problem but in talking to many people and seeing the oil itself is not contaminated you are fine

The problem of condensation can be a simple as the relevant humidity in the air, especially if the vehicle is stored outside and the amount of use.If you only use the vehicle infrequently and \ or for short trips this will allow the condensation to build up.
A good long high speed (within traffic speed limit of course) run will often"burn off" any condensation from air humidity.
The worst scenarios are a leaking head gasket or a cracked head or block. Any good garage mechanic can test for these.

There is a TSB, or technical service bulletin for this. Is common on the 4.7L engines. The dealer can sell you a filler pice that goes in the oil fill to help minimize that residue. I said forget it, and ust continued to keep monitoring it, and cleaning it as needed.

It's understandable if you take short trips and never get the engine up to operating temp for long. If that's not the case you could have a bad head gasket or a cracked head.

nothing to worry about at all on those particular dodge oil fill caps condensation get onto the caps really easily does not affect anything else though
