i didn't do anything to the chain. i only replaced the tensioner.the timebelt was loose. i used the cam tool and the t.d.c bolt. maybe the problem is old...
but i'd like to fix the problem but i don't know how to..

if the timing is wrong and the cam weel is right,T.D.C bolt is in place, there must be a way to adjust the cam?right?

To set it right, check the crank mark - don't worry too much about the lock tool because the crank is unlikely to rotate during the setting process. Next make sure the cam pulleys are free on the cams (use a puller if they are not free). Last place the locating plates on the cams, slide on your bar, set the tensioner and tighten the cam bolts.

You might get away with not releasing the cam pulleys, but the cam locking bar will not slide on as easily - it should take almost zero effort to slide the bar in place if everything is set correctly. Releasing the cam pulleys from the taper is the only way you can turn the cams, to answer your question.

With the cam bar sliding on easily and the crank mark aligned, you have perfect timing.

Good luck!

The locating plates are the 1/4" thick aluminum plates with the holes that the cam locking bar go into. These positively lock on the camshafts using a 'D' shape. I don't know of another plate - nothing else is needed.
