Hi everyone. I too had this problem. Oil was going somewhere in my 3.8, but I had no blue smoke, and the 2007 Grand Caravan had been maintained meticulously. Took it to my independent mechanic, who's treated me right for the last 20 years. He called some friends in the business, and told me the problem was probably in rear valve cover. He showed me the old valve cover, which had a hose connection right in the middle of it, and he said that they could see oil being drawn up the hose, and said that would probably explain it. I just had this done two days ago, so I will let you know whether or not this worked.

It sounds like it's the PCV hose which goes to the rear valve cover, sounds strange that it would be the cause of the oil loss unless there is no pcv valve there and thus all the blow by oil is being drawn into the intake manifold/combustion chamber and being burned. But stranger things have happened with these vans!
