Trouble getting a slant six in the car

I’m having trouble with that screwdriver bit. I’m trying to use a screwdriver in the chain like you said but I’m clearly not doing it right cause it’s not changing anything. Can you give me more descriptive details on how to do it?
You need to get the engine with the tail shaft pointing down at a greater angle then slip the screwdriver in a link behind the engine hoist hook. That will hold the chain from trying to even itself up. But it looks like you got it back in, so no need for that now.
