Car: 2004 ZHP(M54B30 Double Vanos)
I'm having an issue with my car after installing the Beisan systems seals and anti-rattle kit. The actual re-building of the VANOS systems was a breeze especially with the directions provided by Rajaje . No complaints here.
I did however break a VANOS bolt and it fell into the exhaust spline shaft. I ordered the German Auto Solutions double VANOS cam timing tool kit and removed the broken bolt from the spline shaft. I had to re-time the motor and got everything timed correctly. I verified by manually turning the crank clockwise twice and:
-Made sure the cam lock blocks sat evenly with the head
-Verified the dots on the back of the cams were facing upwards
-Verified the harmonic balancer was showing TDC with both cam lobes facing each other
-Used locking pin to lock TDC on bellhousing
I made sure everything was put back together properly using all new gaskets, washers, seals, etc. I installed new spark plugs and verified all of the wiring and connections. When starting, the idle is very rough. It seems like it is misfiring on many cylinders. After the engine runs for a few minutes a very loud "popping sound" comes from the intake manifold area. I immediately turned the car off and haven't started it since. The sound is identical to this:

2 weeks ago I completely overhauled the CCV system with all new hoses and the valve. I cleaned the throttle body and ICV. The car ran flawlessly afterward.
I'm thinking I've missed a sensor or bumped the crank position sensor loose after removing the locking pin from the crankshaft on the bell housing.
If you can provide any feedback at all, I'd appreciate it greatly. I'm sorry if I've not made myself clear or the post is somewhat "wacky". It's 1:45am and I've been at it for 14 hours....
Thanks Mafia,
