Crankcase (pcv) problems of the 2008 Chrysler Town & Country

2008 Chrysler t&c limited w/ 4 liter engine. Since the vehicle was new it periodically produces large plumes of smoke when starting the vehicle. Several trips to two dealerships resulted in no diagnostic action because the problem was not reproducible at the dealership. After several calls to Chrysler and trips to two dealerships, the problem finally surfaced at the original dealership. The diagnosis was a bad pcv valve and it was replaced. However, when picking up the vehicle after the repair, the vehicle again smoked while in the presence of the service manager. The problem still remains at 27,000 miles. The vehicle consumes twice the amount of oil as the owner's 2000 Chrysler t&c with 160,000 miles and three times as much oil as the owner's 1998 Buick century with 135,000 miles. A consumption test was conducted at the 2nd dealership and they reported that the oil consumption was within Chrysler's specifications.
