Ford has issued a service bulletin for some of its popular large vehicles for a problem with ventilation of smoke.
The affected vehicles include the 2010-2014 Ford Flex and Taurus; the 2013 - 2014 Explorer; and the 2010-2014 Lincoln MKS and MKT. Only vehicles with the turbocharged 3.5-liter V-6 are included.
The problem lies in the engine's crankcase ventilation system not properly handling crankcase emissions. Oil is forced up and through the air intake and into the engine's combustion chambers to be burned. Owners may notice excessive oil consumption along with oil smoke coming from the tailpipe at idle.
The problem is alleviated with the installation of a new and improved valve cover, PVC valve, and crankcase vent oil separator. This repair will be covered under the provisions of the new car warranty. It might be covered under the emissions warranty if the vehicle is out of its new-car warranty. Additionally, if the vehicle is covered by an extended service plan, check the coverage outline as it may be covered under either the emissions, powertrain or drivability portion of the plan.
The best way to determine eligibility is to call local dealers with the vehicle in question's VIN (Vehicle Identification Number) and they will run a database search to see if the vehicle is included in this TSB. If an extended service plan is in force, advise the service rep of that fact and they will determine if the repair is covered under the extended service plan.
This repair is labor intensive and can take up to three hours, so plan on leaving the vehicle for the day.
