My Ride: 2001 330i
I used all of those and the camshaft locking fixture. the engine ran for a few seconds before I turned it off, so I'm inclined to believe that the timing was set up properly before the timing chain broke. the alternative theory that I have is that at the low speeds when I hand cranked the engine, the valve to piston interference was not pronounced enough for me to feel it. So that when the engine turned at speed the timing chain snapped as a result of a valve and piston coming in contact
