I provided detailed info on the last question, but that question got lost in the system apparently.
So briefly, I have a 2005 Power Stoke F-350. Loss of power and smoking. Had it in to the dealer 4 to 5 times... no resolution. I think it is the turbo. They replaced turbo parts and a sensor. It is still smoking... also loses coolant through the system somehow?
Any ideas?

Most likely, your loss of power is turbo-related. After you solve the coolant problem, start using full-synthetic diesel HDEO, to prevent future problems with your turbo. If you don't use synthetics, it's only a matter of time before problems develop with turbos. This link will explain further:

What color is the smoke?
