engine cover ID?
was at junkyard and looked at an 08 equinox sport that had the 3.6 motor. DOHC. i have tore enough 3.4 motors apart to tell the difference. anyway, it had a sfi 3400 labeled plastic motor cover laying on top of it. not exactly snapped down in place but for sure on top of motor. i know the 3.6 upper intake kinda points to the rear corner of firewall while the 3.4 points to side, more of a 90 deg angle from motor centerline.
