I tore down a 2.4 liter cylinder ecotec engine out of a 2015 Equinox. In tearing it apart, the part number for each VVT cam actuator were pretty visible and the same on each actuator. So, I assumed that there was no difference between the two cam actuator sprockets/gears. After cleaning all the oil film off the gears, two different numbers appeared on the gears. There is no designation on either gear to differentiate between which would be the exhaust and intake gear. The numbers on both gears is 12621505. But, one gear has the number 42515155 on it and the other has the number 42512036A on it. Can anyone tell me if those two numbers identify one gear as for the intake or exhaust cam?
