foam in the oil filler cap

[airborne1113]

was wondering if any of you liberty owners ever noticed a whitish foam under the oil filler cap and some condensation its a 2005 with the 3.7 ltr eng thought it was sludge but if it is not sure how it would have gotten there ie water/leaks are the only main causes i can think of of hand also i use full synthetic oil as well 5w30

What kind of driving do you do ( short trips, long trips) and what is the weather like. Also how often are you changing the oil?

I have 3.7 05 .I found the same white foam under my oil cap. It is from moisture in the oil fill tube.They made it to long. This is totally normal. Just wipe it clean. :cool2:
