Help!!! Timing Belt off with camshaft or crank not aligned
I took my timing belt off without turning the engine to TDC. How do I get it back to TDC. Do I put back the timing belt and turn the engine? Are there any other ways. Thanks.

OK. I dealt with this when pulling the head: Put the belt back on, rotate it so the crank shows TDC. Then pull the belt off and rotate the cam gear(s) to TDC and slide the belt back on. Rotate the crank until the cam(s) lines up with TDC and check to make sure that both the crank and cam(s) are lined up.
Once it is set on there correctly, you need to tension it. Loosen the tensioner, rotate the cam(s) 360 degrees to TDC. Then rotate the cam(s) another 4 teeth and tighten the tensioner. Rotate the cam(s) another 360 degrees to make sure everything is tight and lined up correctly and you are done.
It is a pain in the ass when doing it your first time but be patient because if it is off a tooth or two, there could be some piston to valve contact and bent valves will result.

what he said is true if your cam is still aligned w/ you crank. if it isn't, do not put your belt back on and rotate, there is (slight) chance you'll tap you valves with the pistons. I had this same problem when i changed mine because when i was taking off the belt cover i pulled the bolt for the pulley all the way out and when i turned the crank later the cams didn't turn with it. what i did was making sure first that all the valves were closed, I turned the motor so none of the pistons were all the way up. Then i rotated the camshaft to the TDC position, then i put the crank on TDC. put the belt on and tightened it per spec. that was my first time ever changing a honda belt and i figured it out, so just be patient.
Also it helps to pull out the spark plugs makes it a lot easier to turn the motor, and since it is easier you will be able to feel if you hit you valves before you do any damage.
