if your gonna slip the t belt off, you need to loosen the tensioner bolt...so tdc bottom end, slip belt off then allign the cam gear to the tdc position, and slip belt back on..retension tensioner...thats how i would do it.OEM cam gear has only ONE position, your not moving it!
Line up your cam/crank as stock, take pics.
Whatever you do DON'T FUCK with the tensioner!
