Cam and Crank
Cam and crank correlation testing — verify timing relationships, identify jumped timing, worn chains, and stretched belts. The cam/crank pattern tells you if the valvetrain is doing what it should.
Remember, cam/crank architecture can be very different. The VVT, sensors can be in the back, or the CKP can be as well. The reluctor can slip. Jumped chain — common.
Due diligence on design is the key.
