My advice is if one is not 100% sure what one is doing, do not spin the crank and cam independently. BMW should have done it fool proof with a possibility to lock cam and crank in place for TB job...like vw did on their diesels.

Ive done a bunch but they’re all different. Porsche flat six timing set with dial indicator. MFI Alfa timing of injection pump needs coordinated with block and head events. Porsche flat four timing is done when case halves joined. Always something new to learn.

Rotate the engine without plugs it's much easier when you aren't fighting compression and hard spots will be legitimate uh oh

Yup usually leave plugs barely threaded to keep debris out, ease turnover
