Hey, I wass thinking about doing the ATF trick to my 7s and I got to thinking: If ATF will foul the plugs and possibly clog the cat, wouldn't it just redeposit a fresh layer of carbon over the inside of the engine when you start it up?

I heard that performing the ATF trick with Amsoil powerfoam instead will accomplish the same thing without fouling plugs etc.

Anybody have any ideas??

 

I've read a thread about using water as a decarboning agent. Search in the 2nd gen spec, I think it's in there.

 

How about using Acetone or Rubbing alcohol

 

The goal is not to make the inside of the engine sparkly clean. The goal is to use the detergent properties of the ATF to break large chunks of carbon that may be prohibiting apex seals from moving.

A better substance to use would be Marvel's Mystery Oil. It's sold in a bright red bottle and was developed long ago as a super/turbo charger lubricant. It is designed to be burned and burns much cleaner than ATF. I use it as an oil additive in my 1st gen. Very good stuff.

 

if you let a carbon coated rotor soak in ATF, see how well it breaks up the carbon. It doesnt do a very good job. Your much better off burning it off. Thats why the tach goes 8k =]

 

is it still safe to use ATF or not? please let me know, 'cause i don't want to kill my rex....
