Need help readjusting cvvt timing on volvo s80

Check fig:----

CVVT always on intake because cam sensors are always intake.

Slacken off, but do not remove, the (3) screws which secure the timing gear pulley to the variable valve timing (VVT) unit.
Press the variable valve timing (CVVT) unit / timing gear pulley on the camshaft.

Install the center screw which secures the variable valve timing (CVVT) unit to the camshaft and tighten slightly.
Turn the variable valve timing (CVVT) unit anti-clockwise as far as it will go.
Remove the center screw.
Position the upper timing cover.
Turn the timing gear pulley clockwise until the screws at the oval holes are in the limit position.
Continue turning clockwise until the timing gear pulley marking is 1 1/2 Cog before the marking on the upper timing cover
Note: Do not turn anti-clockwise during this procedure!
Check that the timing gear pulley is still in the limit position in the oval holes.
Tighten the center screw in the variable valve timing (CVVT) unit to 120 Nm (88 ft. lbs.) .
Check that the variable valve timing (CVVT) unit does not rotate when tightening.
Install and tighten the center plug to 35 Nm (26 ft. lbs.) .
Turn the variable valve timing (CVVT) unit clockwise to the limit position.
Turn the timing gear pulley so that the markings correspond.

Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

There is a tool that locks the crank in the #1 position. There is a plug behind the starter remove that plug push in the tool and that will line the crank. When you turn the crank and line up the cams watch the cam marks, go passed the cam marks 90 degrees and then turn it back, that will set the VVT gear to be in the right position. Now that should line up the crank and the cams. The cam gear tool fits into the slots in the rear side of the cams.
