ive had my trans out once before, that was to change the clutch i blew out, and when we did it we just let the engine tilt down and rest on the motor mounts,

right now i have to pull the trans out again because it needs to be rebuilt, so my question is can i just leave the motor hang on the motor mounts like that? its gonna be awhile and i dont want it to hurt anything, but theres really nothing else i can do......

 

It should be fine, but you might want to steady the engine with a floor jack and a block of wood, especially if u plan on letting it sit for a while.
