I just had my cam phasers and timing chain replaced in a 2012 3.5 eco-boost. With 150,000 miles. I still have a leg at 2500 RPM when I am accelerating it drops down to 2000 RPM but then continues to accelerate just fine. My timing chain slipped three links according to the Ford dealership. Is my 3.5 eco-boost damaged permanently from this timing chain mishap?
Generally it does do damage. You probably have slightly bent valves inside the engine now if it runs but does not run correctly
