What size socket do I need so I can turn the engine by hand. I thought it was 22 but that is too small.

With a good grip you can usually grab the crank pulley and turn it. Not sure on the size but a cheap set of digital calipers will tell you in an instant!

I think it is 27 mm. Either that or 32 mm.

It's 36mm.

It is not 36 mm. I thought my 36 mm socket was missing the entire time I was doing the 6 speed conversion until it turned up in the garage much later. It is 27 mm. Check the link and related posts.


I came home and put a socket on the wrecked 540i crank pulley. It is 27 mm.
