The other day my friend's B20/Vtec wasn't working. The motor was warm, no check engine light, new oil change and we changed the vtec solenoid and still no vtec. We also used different vtec ecu's. Does anybody know what's wrong?? Any help is fine. I was think maybe the oil line was clogged.

do you have a helms manual for a dohc vtec motor? there is a way to check if vtec is working or not, you will need an air compressor. there is a service connector on the vtec solinoid, and with the valve cover off, on the inside of the head, where the vtec solinoid bolts the the head there is a hole, plug that hole and put about 20lbs i think it is, of air into the service connector of the soliniod. this will engage the vtec, you should see the pins lock the center rockers.
