Just out of curosity, what kind of oil are you using? had similar consumtion ( 92 5.0L 184kmi) about a quart every 500mi and the plugs were ashed up bad on #1 and #7 with smoke on start up. I figured it was the valve seals, but out on a whim ( and pure lazyness) i thought i'd give 5w-30 valvoline maxlife synthetic a try. 700mi later only used .25qt and no more smoke. If you dont want to try it or it doesn't work, there is plenty of info on the forum about changing the stem seals with the head on the engine. This is a very common issue with these engines.
