REFITTING

I - REFITTING PREPARATIONS OPERATION

IMPORTANT

Do not scratch the aluminium sealing surfaces.

Wear gloves during the operation.

WARNING

Do not allow this product to drip onto the paintwork.

Failure to follow this advice could block the oil-ways, and rapidly destroy the engine.

• Clean the rocker cover gasket face with DECAPJOINT to dissolve any gasket still adhering.
• Apply the product to the section to be cleaned; wait approximately ten minutes, then remove the residue using a wooden spatula.

Note: The gasket faces on the rocker cover must be clean, dry and free from grease (avoid finger marks).

• Lubricate the cylinder head camshaft bearings with engine oil.

WARNING

Do not put oil on the cylinder head rocker cover.

WARNING

Applying excess sealant could cause it to be squeezed out when parts are tightened. The mixture of sealant and fluid may damage some components (engine, radiator, etc.).

• Using a stipple roller, apply LOCTITE 518 to the gasket face until it turns reddish in colour.
• Use a cloth to remove any LOCTITE 518 in the six bearing channels (4) on the rocker cover.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit the rocker cover.
• Tighten to torque and in order:
  • bolts 22, 23, 20, 13 (8 Nm),
  • bolts 1 to 12, 14 to 19 and 21 to 24 (14.5 Nm).
• Slacken bolts 22, 23, 20 and 13, in order.
• Tighten to torque and in order bolts 22, 23, 20, 13 (14.5 Nm)

III - FINAL OPERATION.

Note: The gasket face on the oil decanter must be clean, dry and free from grease (avoid finger marks).'

WARNING

Applying excess sealant could cause it to be squeezed out when parts are tightened. The mixture of sealant and fluid may damage some components (engine, radiator, etc.).

• Using a stipple roller, apply LOCTITE 518 to the gasket face until it turns reddish in colour.

• Refit the oil decanter.
• Torque tighten and in order:
  • the new mounting bolts for the oil separator in the untapped holes (15 Nm),
  • the new mounting bolts for the oil separator in the tapped holes (10 Nm).
• Refit the engine lifting eye at the engine timing end.

• Refit:
  • the rocker cover disc (5) using the (Mot. 1503) (6),
  • the spark plugs (see 17A, Ignition, Plugs: Removal - Refitting, 17A-11),
  • the ignition coils (see 17A, Ignition, Coils: Removal - Refitting, 17A-2),
  • the intake distributor (see 12A, Fuel mixture, Inlet distributor: Removal - Refitting, 12A-45).

1 - Fitting the camshaft gaskets

• The elastomer seals on these engines come fitted with a flat lip seal (7) and a protector (8) (also used to fit the seal on the engine).

2 - Fitting the exhaust camshaft seal

WARNING

When handling, be sure to hold the seal by the protector (9), as this type of seal is highly FRAGILE.

It is strictly forbidden to touch the elastomer seal (10) in order to prevent any oil leaks once the seal is fitted to the engine.

• Screw the stud (11) of the (Mot. 1632) onto the camshaft.

• Mount the protector with its gasket in place onto the camshaft (taking care not to touch the gasket).

• Fit the cover (12) and the collar nut (13) of the (Mot.1632).

• Screw on the collar nut until the cover touches the cylinder head.
• Remove the nut, cover, protector and threaded rod.

3 Fitting the inlet camshaft seal

WARNING

When handling, be sure to hold the seal by the protector (14), as this type of seal is highly FRAGILE. It is strictly forbidden to touch the elastomer seal (15) in order to prevent any oil leaks once the seal is fitted to the engine.

• Fit the protector (16) fitted with the seal onto the camshaft (taking care not to touch the seal).
• Push the centre of the protector to force the seal into its housing.

• Remove the seal protector, taking care not to drop the seal.

• Fit the stud (17) on the camshaft using the (Mot.1632).

• Fit the cover (18) and the collar nut (19) of the (Mot.1632).
• Screw on the collar nut until the cover touches the cylinder head.
• Remove the nut, cover and threaded rod.
