i have a 91 dx hatch that i just swapped a d15b7 into soley to pass emissions testing then im putting my b16 right back in therrr...well i finally strted her up today aand it idles low and the oil light stays on. flickerd at first then its solid. no matter what engine speed its lit up. i had the oil pan off when it was on the engine stand and the pickup looked fine to me. the motor isnt knocking and runs quiet buut is it safe to say the damn oil pump is toast? ughh id really hate to have to take the bottom end apart again, this time the motors in the car
