o.k. the crank sensor i right above you oil filter and just behind the starter. It just bolts i,n the sensor it self is very very very very hard to come out. My best suggestion to you is to remove the intake manifold, starter and oil filter, this will give you plenty of room to work on it.
Here are the direction from GM's service site.
Crankshaft Position (CKP) Sensor Replacement
Removal Procedure
Caution: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed.
1. Hosit the vehicle.

2. Disconnect the CKP sensor harness electrical connector at the CKP sensor.
3. Remove the CKP sensor to engine block bolt.
4. Remove the CKP sensor from the engine block.
Installation Procedure
Important: Inspect the CKP sensor O-ring for the following condition(s):
• Wear
• Cracks
• Leakage
Replace the CKP sensor O-ring if necessary. Lubricate the new O-ring with engine oil before installing.

1. Install the CKP sensor into the engine block.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
2. Install the CKP sensor to engine block bolt.
Tighten
Tighten the bolt to 10 N·m (88 lb in).
3. Connect the CKP sensor harness electrical connector.
4. Lower the vehicle.
5. Preform the CKP System Variation Learn Procedure .
CKP System Variation Learn Procedure
Important
A Crankshaft Position System Variation Learning Procedure must be performed any time a change is made to the crankshaft sensor to crankshaft relationship. Changing the crank sensor to crankshaft relationship will not allow the PCM to detect misfire at all speeds and loads accurately. Resulting in a possible false misfire DTC being set.
Removing a part for inspection and then reinstalling the same part is considered a disturbance. A false DTC P0300 could be set if this procedure is not performed.
The learn procedure is required after the following service procedures have been performed, regardless of whether or not DTC P1336 is set:
* PCM replacement.
* Engine replacement.
* Crankshaft replacement.
* Crankshaft position sensor replacement.
* Any engine repair(s) which disturbs the crankshaft/harmonic balancer to the crankshaft position sensor relationship.
Caution: Before performing the Crankshaft Position System Variation Learning Procedure always set the vehicle parking brake and block the drive wheels in order to prevent personal injury. Release the throttle immediately when the engine starts to decelerate in order to eliminate over revving the engine. Once the learn procedure is completed, the control module will return engine control to the operator and the engine will respond to the throttle position.
Important
The battery must be fully charged and in good condition. The scan tool connection at the DLC is clean and tight before starting the Crankshaft Position System Variation Learning Procedure.
1. Close the hood.
2. Block the drive wheels and set the vehicle parking brake.
3. Put the vehicle in Park or Neutral.
4. Turn all the accessories OFF.
5. Install a scan tool.
6. Start and run the engine until it is at normal operating temperature 85�C (185�F).
7. With the engine still running, enable the Crankshaft Position System Variation Learning Procedure with the scan tool.
8. Press and hold the brake pedal firmly and raise the engine speed to the specified value, RELEASING the throttle as soon as the engine cuts out.
9. Verify with the scan tool that the crankshaft variation has been learned.
Perform this procedure up to 10 times. If the PCM will not learn the variation, a DTC P1336 should be set. Refer to the DTC P1336 Crankshaft Position (CKP) System Variation Not Learned 2.4L or the DTC P1336 Crankshaft Position (CKP) System Variation Not Learned 2.2L for diagnosis.

Hit 200 NA it broke once, Hit 213 it broke again,
Hitting 300 NA is further away than I thought.
