Hydraulic Tappets

Bleeding

1. Fill a container with 5W - 30 or 10W - 30 engine oil,

and place the hydraulic tappet in it. Press down on

the check ball with a thin wire. Bleed the tappet of

air by pumping the plunger slowly until no bubbles

come out of the hydraulic tappet.

Cylinder Heads

Installation (cont'd)

4. Install the cylinder heads on the cylinder block.

5. Tighten the cylinder head bolts sequentially in 2 or

3 steps.

Specified Torque:

76 N-m (7.8 kgf-m, 56 Ibf-ft)

NOTE:

We recommend using a beam-type torque wrench.

When using a preset-type torque wrench, be sure

to tighten slowly and not to overtighten.

If a bolt makes any noise while you are torquing

it, loosen the bolt and retighten it.

6. Install the head cover gasket in the groove of the

cylinder head cover. Seat the recesses for the cam-

shaft first, then work it into the groove around the

outside edges.

NOTE:

Before installing the cylinder head cover gasket,

thoroughly clean the seal and the groove.

When installing, make sure the head cover gasket

is seated securely in the corners of the recesses

with no gap.

7. Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

Use liquid gasket, Part No. 08718 - 0001 or 08718

- 0003.

Check that the mating surfaces are clean and dry

before applying liquid gasket.

Do not install the parts if five minutes or more have

elapsed since applying liquid gasket. Instead, reap-

ply liquid gasket after removing old residue.

After assembly, wait at least 30 minutes before

filling the engine with oil.

Apply liquid gasket to

the shaded areas.ProCarManuals.com

Pistons and Crankshaft

Removal (cont'd)

11. Remove the bearing from the cap. Keep all caps/bear-

ings in order.

12. Remove the upper bearing halves from the connecting

rods, and set them aside with their respective caps.

13. After removing each piston/connecting rod assem-

bly, reinstall the cap on the rod.

14. To avoid mixup during reassembly, mark each pis-

ton/connecting rod assembly with its cylinder num-

ber.

NOTE: The existing number on the connecting rod

does not indicate its position in the engine, it indicates

the rod bore size.

15. Remove the bearing cap bolts and bearing cap side

bolts, then remove the bearing cap.
