"Not sure if the crank girdle is accessible. If i can see the 3rd journal in on cuddle. This is what a 98 or 99 looks like"

Ok if the crank angle sensor is located on the left side of the motor and clearly visable by the PVC valve then it is either a...1st Gen motor or a 97+ motor. 95-96 motors do NOT have the CAS on the side of the motor, it's hidden.
