so i have a 96 ls block...the guy i got the car off of says its a b16..but i cant find VIN numbers anywhere...imagine that....the only sort of identification if anything is it says pr3-4 on the head..if that helps any..but thats not my problem...my car smokes and smells bad(through exhaust) like its burning gas..not so much oil..it is black smoke, all though some of my friends have told me they have seen blue...but this only happens when vtec comes on....does anyone have any suggestions? i did a compression test and its 125psi through every cylinder..if that helps anything, and i think thats low..not sure im a noob with hondas any help would be greatly appreciated.
