5.4L Triton V8-Powered Fords Called Over Idling Issue

It's a widely known fact that the 330 CID (5.4-liter) version of the Triton V8 wasn't a praised engine because… reasons. Too many reasons, to be frank. Just recently Ford announced that some vehicles from the 2004 to the 2013 model years equipped with the eight-cylinder mill are due for a "free service" after owners complained about rough idling and ticking noises.

First introduced back in 1997 on the tenth-generation Ford F-Series, the first iteration of the 5,408cc Triton V8 featured a two valve per cylinder design. In 1999, the first-generation Lincoln Navigator got a slightly better performing four valve per cylinder and double overhead camshaft variant of the powerplant.

Only recently, the Blue Oval has identified a problem with the three and four valve per cylinder variants of the Modular family V8, advising owners to stop by their local dealership service departments as soon as possible. Vehicles affected are the 2004 - 2010 model year Ford F-150 pickup truck, the 2005 - 2013 Ford Expedition and Lincoln Navigator SUVs, as well as the 2006 - 2008 Lincoln Mark LT luxury pickup.

These cars may exhibit an intermittent rough idle that can escalate to a worrying ticking or rattle noise when the car is in gear and on the move. Owners are warned about the fault by a lit "check engine" light on the dash, but what's the actual problem with the V8? Well, Ford says that the culprits are defective cam-timing solenoids.

Solenoids that work properly help the engine operate at peak power and efficiency. But when something goes wrong and the camshaft timing goes bananas, you should expect lots of drivability issues and over-the-top levels of emissions and exhaust smoke. Affected owners will have their solenoids replaced both on the left and right side of the Triton V8 engine. However, it's a pretty demanding job to replace solenoids, so expect to lose up to four hours for the mechanic to do his thing and repair the vehicle.

Owners that want to find out more info about this technical service bulletin can contact Ford Customer Service at 800-565-3673 or Lincoln Customer Service at 800-521-4140. Don't forget to mention TSB #14-0114 "Intermittent Rough Idle, Rattle Noise While Driving."
