2008 with 262k pretty trouble free miles, for the most part. My last oil sample at 235k came back with an A+ from blackstone. Had a couple tires changed out today and the guy at the shop was going on and on about having the linkage between the turbos checked at a ford dealership. oogled it and cant really find too much about it other than the borg warner box that runs the linkage sometimes goes bad...but it'll throw a code. Anybody have any ideas what he's talking about? I'm pretty sure this guy likes to hear himself talk after listening to him for 5 minutes but I just wanna be sure. And more black smoke in the last 4k miles than normal, by a lot, but im thinking DPF might be suspect. Any and all opinions, im all ears.
