From what I understand, engine exhaust is too hot for any material to withstand without active cooling, which is done as a side-effect of feeding in the fuel. If you just turn it off, then, it's no longer actively cooled, and will rapidly melt from all the other engines around it still going full bore.
This is just a theory.
