I need some urgent help as to how to reinstall a timing belt on my RB20DET Ok the timing belt broke and all my timing is out of wack, I tried lining up the marks on the new belt with the marks on the crank and cams but the timing was way out of wack when I tried to fire the motor up after fitting the belt, how do I align the cams( 2 of them) with top dead center, I can get the crank on TDC but where do the marks on both cams have to be? I know RB30's are easy to change a timing belt but this is a prick as it has 2 camshafts. Any help will be much appreiciated

there should be marks on the backing plate that your timing belt cover screws to. line the dot on the cam gear up with the mark behind it. Well thats how you do it on my RB26 head and im assuming the RB20 head would be the same setup. can get you a pic if you need it

yeah found that out earlier today, tried it, no good looks like ive bent a **** loads of valves!!
