a tool to lock the cams can be made from a 9" long by 1" wide piece of flat iron,you will need to file it down a bit to fit in the slots on the back of the cam and a 5/16X4" bolt will work for the crank locating pin.Here is the shop manual procedure for it.
NOTE: If an original spark plug is reused, install it in the same cylinder from which it was removed. New spark plugs can be used in any cylinder.
NOTE: Use compressed air to remove any foreign material from the spark plug well before removing the spark plugs.
NOTE: Cylinder No. 1 is at top dead center (TDC) when the keyway is in the 12 o'clock position.
CAUTION: If the camshaft timing belt is to be reused, mark the direction of the camshaft timing belt to the rotation of the camshaft prior to removal, or premature wear or failure may occur.
CAUTION: The camshaft must be held stationary at the hexagons with locking pliers. Do not use the alignment tool to hold the camshaft in position or damage to the camshaft may occur.
NOTE: To loosen the camshaft pulleys, hold the camshafts by the hexagon.
NOTE: Rotate the camshafts clockwise as necessary.
CAUTION: Do not rotate the crankshaft; as necessary check that it is still resting against the timing pin.
NOTE: The lug of the belt tensioner should not be hooked in the sheet metal cover during timing belt installation.
NOTE: Incorrect timing belt tension will cause incorrect valve timing.
CAUTION: Tension the timing belt, working counterclockwise.
NOTE: Install a new oil plug seal.
NOTE: Turn the engine two turns in the normal direction of rotation by the crankshaft.
NOTE: Whenever an ignition wire is reinstalled, or a new wire is installed, apply dielectric compound to the interior surface of the spark plug wire boot.
one thing that 9 inch flat steel will not work the cams are below the surface of the top of the head I know my manual shows the cam slots line up perfectly with the top of head?
If you look at the back of the camshafts you will see that the slot is offset,you will need to turn the cams 180* so the slot is on the upside of the cam,then the home made tool will work the same as the factory tool would.
