ATF/Water dribbled down carb to remove carbon?

[MrSony]

IS there any truth to this? I know my dad did it to his '81 Grand Prix with a swapped in Olds 350 and Qjet. Said it made a haunted house out of that HyVee parking lot, but it ran better after that. Is there any merit? I wanna try it on my thunderbird to loosen some crud up.

When poured down the carb water steam cleans the combustion chamber, transmission fluid cleans varnish and carbon. If you use transmission fluid do it somewhere away from neighbors, there is alot of white smoke when you do it. If you put a quart of transmission fluid in the crankcase and run the engine for a few minutes after it gets to operating temp that will clean the bottom end.

Ok cool. Was kinda thinking that but wasn't sure. Thanks. And does my oil have to be a quart low? Or can I do it before I change the oil?

 

[MrSony]

Like the extra quart of atf adding to the oil would make it over full, or will it be fine for just a few minutes of run time?

Is seafoam as effective for cleaning carbon deposits? I've heard good things about it, but never used it on anything but an '02 ford van to clean the fuel injectors.

it'll be ok cause your just idling it but if you are concerned you can just remove a quart of oil before

ok

Years ago I had a knock in the engine that sounded like a rob bearing. An old mechanic that was a neighbor of mine who I asked to help me figure out the knock. He asked me for a glass of water (no bottled water then) and I thought he was thirsty. He took the water and slowly pour it into the carb. The knock was a carbon knock and it went away.
