Pros and cons of complete engine flush
Fast, that is what I am doing now. I think I am going to stick with this solution as it seems to be the least aggressive and the least amount of risk involved. Right now, I put a half quart of ATF in with the new oil, thats supposed to work as well.
Karl, I have used to sea foam on one of my oil changes about a week ago, and so far that seemed to do the best job of removing the sludge (after only 300 miles the oil came out jet black), so I might keep using that stuff.... I cannot seem to find any dealerships around my area that have a flush machine, not sure where to look for one. maybe a quick lube type of place?

be leary of the quick lube places.... they suck by about 98 percent...
Be very careful on engine flushing. If you break loose a lot of crud, it can plug the oil pump intake screen.
I would run diesel motor oil for 3-4 changes, and that will get rid of a lot of the sludge the gradual way.
