Head studs more typically break on the 3.0 rather than pulling out. It's a fair-sized effort to fix, and it's one of those "while you're in there" kinda deals. The longer the car is driven with broken head studs, the more expensive the repair. You may be able to isolate the problem by pulling the coil wire and cranking over the engine with someone underneath, listening for compression escaping between the head and cylinder. Please read the OT thread "Horrible news" before doing this.
