I have a 2003 jeep liberty sport 2 wheel drive and I noticed while driving a huge amount of white smoke like stuff blowing out of tail pipe. then it stopped moving. I looked under the jeep and there was a lot of water running out of the exhaust pan itself. I checked to see if there was water and there was none at all. The oil looks fine and is where it should be and the motor is not hot. I filled it with water and started driving but then it started to do the same thing and the water was empty. what could be causing this ??? Could this be a cracked block or a torn head gasket or is it something totally different ??? someone please help I have a closing on my house in another state and need my jeep to get there if it is fixable.:shock:
