I have a B16 SiR V-TEC engine on my civic and after 5.800RPM white smoke comes out from the exaust. When its cold it runs fine, but after a while the problem begins and the car looses performance. Someone Help Me ...

hmm piston rings? try a compression test but first check the PCV valve by lifting it from underneath, if it compresses easy then its ok, if it doesnt you're probably getting an abnormally high crankcase pressure which is causing oil to get forced into the combustion chamber- hence the white smoke...
