been getting a glow plug module code, started out replacing glow plugs and harnesses. started with right bank. pulled plugs and thanks to some misinformation by the parts guy thought had a gasket leaking causing oil on the plugs which was puzzling. come to find out thats normal when you pull them. anyhow got all the way to pulling rocker assembly and then reversed order, and went back putting everything in. missed the part about setting the dampner at 6 o clock and now that its back together motor is sluggish. with throttle all the way to floor it seems like the turbo is not even spooling. not sure whats goin on here curious if maybe that might have bent the pushrods causing this or maybe this sounds more like an air restriction somewhere. if anybody could help that would be greatly appreciated.

no vacuum source from port for map sensor, can anbody help explain why that might be and how the vac system works on these 6.0's. thanks.

 

Since diesels do not have a throttle butterfly to restrict the intake there is no vacuum. The map sensor on a turbo diesel is to read manifold pressure from turbo boost. I am not sure why you have a power loss but if the turbo is spooling up you should be able to get pressure from the map hose.

 

Bad vac pump??

 

Updates??

 

turbo is throwing code p2263 we pulled the intake pipe and its blowing air, the code states that its a performance issue. still lost and still have no power

 

IDK, might have to make a trip to the dealer.

 

Updates??

 

Going to close the thread for now. Can reopen and update.
