High Pressured Blow Off Sound and Oil?
 
High Pressured Blow Off Sound and Oil?

After driving around in the mountains for a few hours I came to the intersection of a major road. Upon waiting for traffic, I gave the jeep gas for a normal take off. I immediately heard a sound that was similar to a High Pressure Blow Off valve that seemed to come from the driverís side. It only lasted for a seconds. I may have just been paranoid, but it seemed to have some overall vibration coming through the seat. Even my wife thought so, but the steering wheel was completely vibration free. Since it seemed normal enough I drove the remaining 5 miles home. Once home I walked around the jeep and did not see anything. However, once I crawled under the jeep I noticed a viscous liquid on the Driver side motor mount. It was coating most of the motor mount and really nothing else I could see. The liquid is similar to brake fluid, but not quite, and not quite motor oil. If I had to lean one way or another Iíd say brake fluid.

There was no liquid on the engine block itself and I could not find any liquid on the Power Steering or brake lines? This is basically right under the air intake.

I checked the fluids in everything and it seems within specs and had not moved since the last time I checked. At this point I am at a total loss, but am worried something major is in the works.

Any thoughts will be appreciated.

Not that I can find. From some other forums they are saying it might be my A/C which happened to be on at the time.

it might be the front axle vent tube

From some other forums it seems to be my AC high pressure relief valve. Now to figure out what caused the pressure to spike enough to blow the valve.
