  12.  
  13. Using a suitable tool, hold the oil pump drive shaft gear still and remove the retaining bolt. Remove the gear.
  14.  
  15. Remove the timing chain cover seal as follows:
  16.  
    1. Using a suitable punch and hammer, tap out the old oil seal from the cover.
    2.  
    3. Using a suitable seal driver and hammer, drive in a new oil seal until the surface is flush with the edge of the timing chain cover.
    4.  
    5. Apply some high temperature multi-purpose grease to the lip of the oil seal.
    6.  


To install:

  1. Install the oil pump drive gear and tighten the 16 ft. lbs. (22 Nm).

    4.  
    5. Install the camshaft timing pulleys with the guide facing the direction as indicated. The exhaust side will be with the pulley guide facing the No. 2 timing belt cover. The intake side will be with the pulley guide facing the front side.
    6.  
    7. Align the matchmarks of the No. 2 timing belt cover with those of the camshaft timing pulleys and of the crankshaft pulley. Be sure that the No. 1 cylinder is set to top dead center on its compression stroke, which it should be if the engine has not been disturbed.
    8.  
    9. Install the timing belt with the belt having the proper tension between the crankshaft timing pulley and the camshaft timing pulley on the exhaust side.
    10.  
    11. Loosen the idler pulley set bolt and stretch the timing belt. Tighten the idler pulley set bolt to 36 ft. lbs. (49 Nm). Be sure that the timing belt tension is applied evenly throughout the belt.
    12.  
    13. There are 3 pin holes on the camshaft and timing pulleys. Select the one overlapped hole and insert the pin into it.
    14.  


If there is no overlapping hole, find one that is nearly overlapped and rotate the crankshaft slightly to overlap it and insert the pin.

    1. The crankshaft pulley angle can be adjusted approximately 3° by changing the pin hole to the next one.
    2.

  16.  
  17. Reconnect the negative battery cable. Connect a timing light and tachometer.
  18.  
  19. Start the engine and set the ignition timing. Recheck the idle speed adjustment. Check for leaks and add coolant as necessary.
