Remove the bolt and the camshaft position sensor.

Using several steps, loosen and remove the 11 bearing cap bolts uniformly in the sequence shown in the illustration, then remove the No. 1 camshaft bearing cap, No. 2 camshaft bearing cap and No. 2 camshaft.

NOTICE:

Loosen each bolt uniformly while keeping the camshaft level.

Clamp the camshaft in a vise, and confirm that it is locked.

NOTICE:

Do not damage the camshaft.

Remove the bolt and the camshaft timing sprocket.

Using several steps, loosen and remove the 8 bearing cap bolts uniformly in the sequence shown in the illustration, then remove the No. 2 camshaft bearing cap and the camshaft.

NOTICE:

Loosen each bolt uniformly keeping the camshaft level.

Clamp the camshaft in a vise, and confirm that it is locked.

NOTICE:

Do not damage the camshaft.

Cover the 4 oil paths of the cam journal with tape as shown in the illustration.

HINT:

One of the 2 grooves located on the cam journal is for retarding cam timing (upper) and the other is for advancing cam timing (lower). Each groove has 2 oil paths. Plug one of the oil paths for each groove with a piece rubber before wrapping the cam journal with the tape.

Puncture the tape covering the advance oil path and the retard oil path on the opposite side from the advance oil path.

Apply compressed air at about 150 kPa (1.5 kgf/cm²) pressure into the 2 broken paths (the advance side path and the retard side path).

NOTICE:

Cover the paths with a piece of cloth to prevent oil splashes.

Confirm that the camshaft timing gear revolves in the timing advance direction when the air pressure on the timing retard path is reduced.

HINT:

The lock pin is released and the camshaft timing gear revolves in the advance direction.

When the camshaft timing gear reaches the most advanced position, release the air pressure on the timing retard side path, and then release the air pressure on the timing advance side path.

NOTICE:

Camshaft timing gear occasionally shifts to the retard side abruptly if the air pressure on the advance side path is released first. It often results in the breakage of the lock pin.

Remove the bolt and the camshaft timing gear.

NOTICE:

1. Do not remove the other 4 bolts.
   
2. When reusing the camshaft timing gear, unlock the lock pin inside the camshaft timing gear first.
   

Using several steps, loosen and remove the 10 cylinder head bolts uniformly with an 8 mm (0.31 in.) bi-hexagon wrench in the sequence shown in the illustration. Remove the 10 cylinder head bolts and the plate washers.

NOTICE:

1. Do not drop the washers into the cylinder head.
   
2. Head warpage or cracking could result from removing bolts in the wrong order.
   

Using a screwdriver with its tip wrapped with protective tape, pry between the cylinder head and cylinder block, and remove the cylinder head.

NOTICE:
