I would run down to auto parts place or harbor freight and grab a compression tester. You can definitely feel the compression stroke when turning by hand and hear the air slowly escaping around the piston rings.
Possible like other member mentioned you got a TU crank, which should work fine but the harmonic balancer or flywheel from a TU engine may need to be matched to it if BMW changed the position of the keyway or dowel pin on the newer cranks.
