The Ford Barn - View Single Post - Cleaning oil pan sludge without dropping it- before changing to detergent based oil

Don't switch to detergent oil until you can clean the pan and valve chamber of the accumulated sludge.
What no one has directly mentioned is that if you switch to detergent oil, the sludge in the valve chamber may break up into globs and one of them may float over a main bearing supply tube and starve the bearing causing failure. As mentioned on earlier posts, the debris held by the sludge would also be put into suspension and passed through your bearings and against other mating surfaces. Not good!
Good Day!
