​

1. Remove the 2 nuts and cover.

1. Remove the 4 bolts and 4 ignition coils.

1. Remove the 2 bolts and disconnect the 2 engine wires.

2. Remove the 8 bolts, 2 nuts, and the cylinder head cover.

1. Turn the crankshaft pulley until its groove and the timing mark "0" of the timing chain cover are aligned.

2. Check that each timing mark of the camshaft timing gear and sprocket is aligned with each timing mark located on the No. 1 and No. 2 bearing caps as shown in the illustration. If not, turn the crankshaft by 1 revolution (360°) to align the timing marks as above.

1. Remove the 2 nuts, tensioner and gasket.

   NOTICE:

   Do not turn the crankshaft without the chain tensioner.

1. While holding the camshaft with a wrench, loosen the camshaft timing set bolt.

2. Using several steps, uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.

3. Remove the 5 bearing caps.

4. While holding the No. 2 camshaft by hand, remove the camshaft timing sprocket set bolt.

5. Remove the camshaft timing sprocket from the No. 2 camshaft with the timing chain wrapped on the sprocket.

6. Remove the camshaft timing sprocket from the timing chain.

1. Using several steps, uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.

2. Remove the 5 bearing caps.

3. Remove the camshaft and camshaft timing gear while holding the timing chain by hand.

4. Tie the timing chain with a string as shown in the illustration.

   NOTICE:

   Be careful not to drop anything inside the timing chain cover.

1. Clamp the camshaft in a vise, and make sure that the camshaft timing gear does not rotate.

2. Cover all the oil ports except the advance side port shown in the illustration with vinyl tape.

3. Apply air pressure of 100 kPa (1.0 kgf/cm², 14 psi) to the oil path, then turn the camshaft timing gear in the advance direction (counterclockwise) by hand.

   CAUTION:

   Cover the paths with a shop rag or piece of cloth to avoid oil splashes.

   HINT:

   Depending on the air pressure, the camshaft timing gear will turn to the advance angle side without applying force by hand. Also, if the pressure is difficult to apply because of air leakage from the port, the lock may be difficult to release.

4. Remove the flange bolt of the camshaft timing gear.

   NOTICE:

   1. Be sure not to remove the other 4 bolts.
      
   2. If planning to reuse the gear, be sure to release the straight pin lock before installing the gear.
