i test drove a 94 YJ, very nice condition and ran great. the only prob is that it has 187,000 miles and under the hood i found a homemade something or other. the hose that runs from the top of the valve cover goes straight to a plastic container. also on the top of this container were two small holes in which steam was escaping. is it blowin oil or what? should i steer clear of this jeep? btw they are askin $4,900 but im sure it can be talked down.
