Factory manuals werent written with high mileage or poor maintenance engines in mind. I dont think using a mild engine cleaner if needed & following the instructions is a bad thing or will cause any damage, seafoam for example is like 1oz/qt, that wont harm the engine or weaken the oil enough to cause harm for the short time its ran. IIRC seafoam uses 25-35% naptha along with other mild ingredients for cleaning.
ATF on the other hand has zero additives that engines need, even used for 30 minutes it is not protecting the engine at all, the cam/lifters are under constant full forces, literally grinding the surfaces against each other with no protection at all. Looks like using pure ATF is now being questioned by the guy that used it if it may be causing the current noises...
