I believe the 94-95 civic ex had the VTEC on it. And the DOHC VTEC civics, preludes, integras, have them on it. The 6th gen civic won't have it on it's valve cover. Just know this, if you got an EX, assuming you have a 5th gen +ex YOU HAVE VTEC. Dont' know about the earlier gens. The only reason you wouldn't have vtec is if the previous owner swaped out the motor.
STOP ASKING IF YOU HAVE VTEC OR NOT. lol. How many threads has there been about this? Look at engine tech and look for the engine code sticky.
K byE!
