Pull and check your spark plugs. See if one or more are "white" - if they are, you're probably leaking coolant into those cylinders. Then do leak down test and watch those cylinders closely- I'm doing my 3.0L fot the second time right now (dealer did it 1st time under warranty about 100,000 miles ago). Good luck.
