Very suddenly, last night, my jeep suddenly started making a load clank. It worsened as I put took it from park into reverse/drive. So I decided to pop the hood. Suddenly lots of watery brown substance dripped from my engine. So I turned it off. Looking at the engine it seems to be spraying out from around the crank area. It's still sitting at my sister in-laws. I didn't want to drain the water and burn my engine up on the way home. I found a couple of very tiny cylinder shaped bearing in the substance.(I don't know if it even came from my jeep) Is this a water pump problem? Crank shaft? thermostat housing? Hopefully something cheap.
