According to Ford.. it "was" the turbo. And yeah... We are still seeing it "play out". You can ask a few of my other friends that purchased turbocharged vehicles and found themselves in the repair shop. (Both Ford and GM products). Many old school mechanics will tell you they have seen tons of "tech" come and go... "New" isn't always "better". In fact, I'd venture to say that newer technology is implemented to cut costs or meet some mandate vs. being "better".They (the mechanics) would choose the V8 because most mechanics working on your truck would be old school minded “turbos are bad” I’m set in my ways type of people. The only thing they know less about is oil
There are who knows how many turbo platform vehicles out there at 100k+ miles. It’s not some new technology that we are still seeing play out. It’s not even the turbo that is the issue on the vehicle in question.
