I understand about products like "Restore", Bars Leak, and similar gap filling products working, but are you advocating the use of products designed to flush and dissolve/remove sludge build-ups from an engine? I've torn down many old engines with heavy sludge build-up. Although messy to work on, I never considered sludge to be a serious problem (unless of course it broke loose and clogged something). In my experience sludge typically doesn't do that..........unless something designed to dissolve it has been added. I'd be interested in more information regarding your experiences with crankcase flushing products. Tim

If you're just thinking of trying to break loose stuck piston rings, what are your thoughts on simply putting a couple teaspoons of Seafoam or a similar product in each cylinder via the spark plug holes............then letting it sit overnight?
