Way to go. Coincidentally, I heard a story about a MD mechanic who has become quite proficient at removing gp from the 606. I don't have the whole story, but it goes like this...
Remove the injectors, fill the cylinder with diesel, let sit overnight, vac out diesel, reinstall injector, drive until operating temp reached, remove gp like normal. Not saying anything but that I've heard this story and the mechanic charges $1200 for the job.
