After left side banks chain was installed on right side three o'clock position the black link do not match with sprocket timing mark ( one link ) I Left it like this and installed the tension-er and guides them I rotate the camshaft sprocket counterclockwise to eleven o'clock position to check all marks of left side again as instructions said, but I find all three black links marks out of exhaust and intake timing marks, is this normal? I rotate three time more but the black link continue far out the all point marks, This is okay or I have to start again? Thank so much for your help.

Start over. Much easier than damaging the engine because of bad valve timing.

Thank you but I need to know if after you match the 6 black chain links with all timing marks because you rotate the botton Cranshaft suppose the motor valves go out of timing?

On initial install the marks should all line up. So you install one chain with the marks lined up, then install the second chain with the marks lined up. If they all line up then and the tensioner is released you are done. You should be able to turn the engine backwards one turn, then turn it the normal direction one turn and the marks will line up. However if you rotate the engine the correct direction the marks will not line up.
