I've never even removed my VC, nor inspected the VANOS gear. However, if the Intake cam quit turning, and the engine kept on turning (and has been cranked with Starter) after the last bolt came out/ broke, I fear for the state of your Intake Valves in the "Interference" engine (where pistons will contact valves if the VALVES are NOT timed correctly.

"Cranks fast" in your thread title worries me. Got a USB Endoscope ($20)? Got a Compression Tester? Hope I'm wrong, and you can explain HOW Intake Cam held its timing after all FOUR (4) Cam Sprocket bolts broke.
