I have a 2011 Camaro with a row of teeth off of the flexplate... Is there a way to rotate the engine that I am missing? all I see is a small round inspection cover, I tried turning it over with the crank snout bolt but was afraid of snapping it or damaging the harmonic balancer. My thoughts are to replace the flexplate while the trans and engine remain in the car with 3 to 4 inches to work with.
