How to align timing sprocks on a 1997 z24 chevrole cavalier

You will need 2 5/16 drill bits. There is a 5/16 hole in each cam gear. With the crankshaft 1/8 turn off TDC, turn the cam gears so the hole is down. Insert the drill bit into the hole and move the gear slow until the bits slides into a hole in the rear timing cover. Do this to both cam pulleys. When you have both bits installed, this will lock the cams. Don't turn the cams with the crank at TDC, It will bend valves. Once you have the cams locked, turn the crank 1/8 of a turn back to TDC. Don't go the other way. The TDC mark on the crank should be a dot on the gear and a arrow on the rear timing cover. Then after everything is lined up, Install the chain,guides and tensioner. After everything is installed, Turn the crank two revolutions, and line the crank back up to TDC. If the timing is right, you should be able to insert the drill bits in each cam gear. Hope this helps.
