Mayonnaise on Oil Cap

  • 6 CYL

  • 80,000 MILES

I have a 2005 Jeep Liberty with the SOHC V6 3.7 liter with 80,000 miles. A couple of months ago when I checked the oil I found Mayonnaise on the oil cap. Sometimes when I check under the cap there is actually drips of water on the bottom of the cap. The first thing I thought about was a blown head gasket, but a couple of months use and over 2,000 miles there has been no noticeable coolant loss. Also when I change the oil it seems to not have any water in it. I drive over 25 miles per day one way.

Also starting this winter when I fill the gas tank the gas comes pouring out after the tank is full and shuts off.

I don't know if these problems are related but I have read that blocked vents or tubes can cause these issues. Is there a common vent or tube or something else that could be the issue of both of these? I'm stumped?

Do you
have the same problem?

Blocked vents can cause the gas problem, but I would contact chrysler about the gas problem as thee may be a recall for that as alot of Jeep owners are experiencing the same problem. For the mayonaise is it hellmans? Lol. Seriously check your pcv system this may be just a cold weather thing so maybe you need to change the pcv valve and check to make sure the hose isn't blocked or sucking together.

Was this
