Yo bud, the ATF 'clean' is most certainly not useless!

It will clean the inside of the combustion chamber like new.

If I am doing any head work, I do that clean first and when I open it up it is super clean which makes for easy inspections and easy head gasket changes.

I did mine a couple years ago for a head gasket leak and when I opened it up there were a couple loose chunks of carbon still laying around inside. They were almost 1/8" thick and hadn't gotten blown out the exhaust yet because I didn't drive it after the clean.

It also does 'wonders' for city driven vehicles that develop a ping or timing knock.
