So, we were headed into town this evening in our 2011 Super Duty 6.7L, and as we were going up the mountain we heard what sounded like a metallic pop, and then felt a slight loss in power. I suddenly had to give it more throttle to maintain the same speed going up the mountain. After a little bit of checking around the instrument cluster, I noticed we had absolutely no turbo. The rest of the way into town, which included climbing another mountain, the Super Duty did fine. It still had power to get it up to 70 going up the mountain but without the turbo. After the truck sat for about an hour while we were eating dinner, we got back in it for the return home. When we first gave it the throttle after it had cooled down, it hesitated quite a bit. I had to give it wide open throttle to get it going, then after it warmed back up, it ran fine, all the way home. Just without the turbo. What could have happened to the turbo? What drives this turbo?

 

Exhaust gas going out must go past the turbo, but is controlled by by a bypass if pressure exceeds a certain limit.

SOMETIMES A HOSE CLAMP WILL LET GO AND ALL PRESSURE FROM THE TURBO IS ALLOWED TO BYPASS THE INTERCOOLER THEN INTAKE..

A quick visual inspection of all hoses from the turbo to the rest of the components will help if the problem only involves a loose or broken large hose clamp.

 

Thank you. I will try to take a look at it tomorrow.

 

So is it the exhaust flow that drives the turbo?

 

It would be a good idea if you considered doing a little reading to get some idea of how they work and things to do to extend turbo life.

They can be expensive to replace and anything you can do to prevent premature failure really pays off.
