Rb25 Knocking Sound?

[salah]

hey guys,

i have a 96 r33 s2, and i changed my water pump yesterday (my first time doing this). now before taking off the timing belt i didnt top center the engine (stupid mistake). but when i put everything back together the everything was still in its natural state, i didnt move any of the pullies indepedantly. i also got a mate who's a mechanic to check it out before i start the car, and all the marks aligned properly. the first time i turned on the car there was a loud knocking sound from the engine, and it got louder with the revs. but this sound seems to kind of stop after the engine warms up properly. ive included a video so you guys can hear for yourself. whats the chances its the valves? or the shifters? could i have caused this when i changed the water pump?

Check you tightened up the bottom timing belt cover properly, otherwise it will bang on the balancer and sound like you did something horribly wrong. I did this a while ago and it sounded similar to this

but the sound seems to be coming from the engine, and not where the cover is.

anyone else???

well the obvious thing to suggest is check the cam timing. again. its not like the valves or lifters stuffed up when you did the pump.
