  3. Hold the chain tensioner ratchet lock mechanism away from the ratchet stem with a small pick.
    4. CAUTION: During tensioner compression, do not release the ratchet stem until the tensioner piston is fully bottomed in its bore or damage to the ratchet stem will result.
  4. Slowly compress the timing chain tensioner.
  5. Retain the tensioner piston with a 1.5 mm (0.05 in) wire or paper clip.

  6. If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the LH and RH timing chains.
    1. Mark any link to use as the crankshaft timing mark.
    2. Starting with the crankshaft timing mark, count counterclockwise 29 links and mark the link.
    3. Continue counting counterclockwise to link 42 and mark the link.

  16. Remove the LH and RH timing chain tensioner piston retaining wires.
  17. Rotate the crankshaft counterclockwise 120 degrees to top dead center (TDC).
    18. CAUTION: Failure to verify correct timing drive component alignment will result in severe engine damage.
  18. Verify the timing with the following steps.
    1. There should be 12 chain links between the camshaft timing marks.
    2. There should be 27 chain links between the camshaft and the crankshaft timing marks.
    3. There should be 30 chain links between the camshaft and the crankshaft timing marks.
