Also, to check for a leaky doser injector, pull the pipe away from the turbo where you can see the tip then crank up the truck. If it is leaky, you will see the tip get wet/damp inside the pipe.

Also, if your getting gray smoke and it is not the exhaust, with a lot of miles on the engine, you may have lost an exhaust valve seal. To check for this, you will have to oull the exhaust manifold and look for wet stems.
