How to remove a Mini’s engine and front subframe.
Step 1: remove everything that’s not the engine. Unbolt the subframe from the body.
Step 2: Realise you need the rear wheels to do this properly. Put the rear subframe and suspension back in, then use an appropriate hoist to lift the body up. If an appropriate hoist is not available, use a piece of string and some pulleys you found. Don’t worry, the shell is extremely lightweight and this photo wasn’t posed at all.
Step 3: the engine will now gracefully exit the engine bay- unless, like everyone else, you forgot to undo the earthing strap or brake lines.
