I replaced my Shut Off Valve (finally). I've been told to prepare ahead of time for a runaway diesel, and have someone else start the car. There've been terms and abbreviations used that I don't know what they are. (I'm lower than a low level mechanic, but I get the job done...eventually).

One person said to take off the flex tube that goes into the turbo and be prepared to block it with a spray paint can lid. Another person said no way, there are air leaks further up the food chain, so the car could still pull in air.

Some of you said to take off the turbo cross over tube. Seems to me there are 2 parts past the turbo. One is a short 5" hard tube, then the curved thing that goes up and over the engine. I'm assuming that's the cross over tube? How hard is that to take off?
