I think it does more harm than good really.... A poorly maintained engine with sludge and varnish in it still runs..... Removing the sludge and varnish could damage the engine further by reducing compression if your sludge and varnish happened to be in an area where it was providing some kind of seal.....
Leave well enough alone..... Change your oil in a reasonable timeframe and leave the engine cleaning to the people who end up doing the overhaul when its time......
