Motor flush for a previously neglected engine

PYB with or without Kreen... I also believe BG has a good engine cleaning product but can not remember the name.

If neighbor is insisting on clean go see someone to do a notarized letter stating he wants it done at x price but if motor takes a dump he is responsible. All seriousness I have cleaned sludge motors and don't recommend it as sludge goes straight to screen clogging oil pump. Toyota had a problem awhile back while I was a tech at Toyota dealership and they wanted us to pressure wash motor in car with pan off as well as valve cover. Can't tell you how many oil burners this left as well as a few knockers Toyota bought. Not worth risk. I say no smoke or oil usage leave alone just change oil regularly and enjoy however long it last. If using oil look to replace or rebuild engine.
