Expert:  Ray M. replied 5 years ago.

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.

Removal

  1. Grasp the spark plug boot firmly and with a twisting pulling motion, disconnect the spark plug wires from the spark plugs.
  1. 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.

    Remove the spark plugs.
  1. Remove the valve cover. For additional information, refer to Valve Cover in this section.
  1. Disconnect the heated oxygen sensor (HO2S) electrical connector.

  1. Remove the catalytic converter. For additional information, refer to Section 309-00.
  1. NOTE: Cylinder No. 1 is at top dead center (TDC) when the keyway is in the 12 o'clock position.

    Position cylinder No. 1 just prior to TDC.
  1. Remove the stud bolt.
  1. Install the crankshaft TDC timing peg.
  1. Rotate the crankshaft clockwise against the timing peg.
  1. 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.

    Relieve the tension on the timing belt tensioner pulley.
    • Loosen the tensioner pulley bolt.
    • Release the tension on the timing belt by disconnecting the tensioner tab from the timing cover back plate.
  1. Remove the timing belt.
    • Slide the timing belt off the camshaft sprockets and the crankshaft sprocket.
  1. Inspect the timing belt for wear. Install a new timing belt as required.

  1. NOTE: Cylinder No. 1 is at top dead center (TDC) when the keyway is in the 12 o'clock position.

    Confirm the crankshaft position is at TDC (No. 1 cylinder) by rotating it clockwise against the alignment peg.
  1. 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.

    Position a new timing belt in place.
    • Starting from the crankshaft timing belt pulley and working counterclockwise, position the timing belt in place while keeping it under tension.
  1. NOTE: Incorrect timing belt tension will cause incorrect valve timing.

  1. CAUTION: Tension the timing belt, working counterclockwise.

    Using the hex key, rotate the adjusting washer counterclockwise until the notch in the pointer is centered over the index line on the locating tab (the pointer will move clockwise during adjustment).
  1. While holding the adjusting washer in position, tighten the bolt.
  1. 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.

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?

 

Expert:  Ray M. replied 5 years ago.

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.
