using oil
i have a 2003 F-150 4.6 4x4, that has started using about a quart of oil a week, i can't find any leaks, there is no smoke, where could the oil be going? The truck has a 101,000 miles on it.

On the 4.6 engine, the PCV valve is on the right side valve cover, the hose goes around the back of the engine to the upper part of the intake manifold.
Actually there is only hose at each end, with a metal tube in between them. The rubber hose ends deteriorate over the years and may need replaced. The PCV valve can be flushed out with some carb cleaner.
