http://www.m42club.com/forums/showthread.php?t=10828 do not use loc tite!!! you will never get it back out!! the bolt will break if you use it!!! it is a stretch bolt like cylinder heads, that is why it must be replaced when taken out. its 8 bucks from bma. torque is 160fp to tighten. I use a block of wood most of the time to stop the breaker bar. it may take a few trys with the starter you got to go manually move it back to the breaker bar can pick up speed before stopping. you dont need to take out radiator to do this either!! 22mm deepwell socket is the crank bolt size
when the motor is out of the car there is a hole under the intake where a screw driver or cam stops fit. there is a hole in the flywheel that it will slid in to and then you can crank away with a impact. or use a flywheel tool and have someone hold it while you impact the shit out of it. ive done it both ways a few times
standard thread! again no loctite replace bolt! cant stress that enough!
