turning the engine by hand is necessary in case you got too much fluid in a cylinder so you don't break a piston or bend a rod. mmo will just act like diesel fuel and burn . What the other fellow did was actually pour the seafoam down the intake of a running diesel which is a huge 'no no' and he's very lucky he didn't immediately destroy his engine.
let the mmo sit in the cylinders for a few days to maximize penetration. then turn the engine by hand a few times to make sure there's no binding then start as normal
