Upon researching best way to bolt on a new sprocket on tuners we put the timing belt back on while I made sure the cams didn't move and my brother torque down the sprocket bolt. In the couple of attempts we did the sprocket slipped off the belt and turned. That feeling didn't sit right so I left it at that for now. I'm hoping we didn't screw anything up. Now the crank shaft timing marker ofcourse is no longer aligning up with the camshaft timing markers. How much damage to the valvetrain can I do by hand if I try to align the crankshaft marker withouth the TB on? Otherwise I think we'll need to pull the head and start all over.
