2016 Ford F-150 XLT 2.7 Ecoboost 3.55 Axle
Told a couple people this already, but I was going up a hill, was lugging the truck pretty good, and then I hear like a click click noise from the engine and a plume of smoke out the back. No change in rpm or boost, nothing, just a weird click click noise and black smoke. I wasn’t data logging at the time, but I experienced this issue a little before I had the cylinder heads replaced. Thought that the new heads resolved it. Any ideas?
