My brothers 2004 Liberty has been smoking recently, we've recently replaced the oil pressure switch and just yesterday we decided to replace the valve cover gaskets thinking it would correct the problem. After doing the gaskets and changing the oil, the Jeep is still smoking from somewhere around the passenger side exhaust manifold area. It almost looks like its coming from the o2 sensor or pretty close to it. Anyone have any ideas?
