I took off the front cover, and I'm sure CAS gear has moved while I was trying to clean the cover. I'm guessing this means I need to set the TDC again. How do I do this with Microtech? That information isn't really available on the manual... I'm guessing I set the e-shaft keyway on the passenger side of the car then line up the marks on the CAS? how would I know rotors won't be 180deg off?
