can I put ATF in the motor for one month?
 

I've read some old treads, most peoples just soak for 1 or 2 days? because I am going to vacation , I plan to do the ATF trick ,just wondering is it too long to soak the motor?thanks for input.:)

That's the best way to store an engine... fill it up with ATF, pull the plugs and spin it over, put the plugs back in and don't worry about it.
