- Replace with new cylinder head and manifold gaskets.
- Thoroughly clean the mounting surfaces of the cylinder head and cylinder block.
- Set the piston of cylinder No. 1 to the TDC position of the compression stroke.
Attention:
- Make sure that foreign particles do not get between the gasket and the cylinder head/cylinder block.
- Try not to damage the contact surface under the block and cylinder head gasket.
- The gasket has metal components, so do not bend it.
- Check the washers for wear and damage, check the seating surfaces of the washers.
- Before installing the top and bottom covers, be sure to wipe them with a cloth.
1. Install the cylinder head gasket and dowel pins on the cylinder block.
2. Install the cylinder head to the cylinder block and align exactly with the dowel pins.
3. Apply engine oil to the threaded sections of the bolts and seating surfaces of the washers. Tighten the bolts in the order shown in the figure to 29 N·m (3.0 kg m).
- Retighten the bolts to 29 N·m (3.0 kg m).
Attention:
- Use a TORX key.
- If the bolt squeaks, loosen it and retighten it.
4. Tighten the bolts twice 90°in the above sequence.
- If the bolts have been replaced with new ones, tighten an additional 90°.
5. Tighten the bolt connecting the intake manifold and the rack (see above).
6. Install the exhaust manifold strut and tighten the self-locking nut (see above).
7. Install timing belt (see above).
8. Install the valve cover gasket, aligning the corners exactly.
Attention:
- Before installing the gasket, clean the grooves in the valve cover and wipe the gasket with a rag.
- When installing the gasket, make sure that it does not move or rise at the corners.
9. Apply sealant to the corners of the gasket.
Attention:
- Use genuine Honda sealant 1216, 5699, 1216E, or 5999.
- Do not use old sealant.
- Remove dirt and oil from sealant application areas.
- Do not install the gasket if more than 5 minutes have passed since the sealant was applied. Remove sealant and reapply.
- Fill in engine oil after 30 minutes. and more after installing the valve cover.
10. To prevent the gasket from falling out during installation, hold it with your fingers at the contact points with the camshaft bearings (semicircular sections). Install the cylinder head cover and wiggle a little to seat the gasket.
Attention:
- Before installing, wipe the contact surface of the cylinder head with a rag.
- Do not touch areas where sealant has been applied.
- Check washers for wear and damage. Check the seating surfaces of the washers.
- Before installing the valve cover, apply engine oil to the sealing lips of the spark plug tubes with your finger.
- After installation, visually check the seals for looseness.
- Remove excess oil.
11. Tighten the bolts in the order shown in the figure.
- Tighten in 3 steps.
