Find a mopar online parts store and look at a parts diagram for your 3.7. Should show exactly where it is...

The PCV valve has been relocated to the rear of the engine on the driver's side, between the valve cover and the intake manifold. They replaced that nice little plastic valve (cheap) on the front of the engine (easy access) that has worked so well for so many years with a large metal and plastic one (expensive! and hard to get at) that takes about a 1 5/8 inch deep well socket to remove. You will likely also have to replace the hose going to it (also expensive), as it will likely self destruct in the removal process. But mine now has around 110,000 miles on it with no problems, so it might be worth it.
