3. Angle tighten 130° . Use protractor 9512050 .
Scheme 72
Lubricate the valve guide wells.
Install all the tappets.
Lubricate the camshaft bearing seats.
Install the intake camshaft. Ensure that the groove at the back of the camshaft is above an imaginary center line.
Position the exhaust camshaft. Ensure that the groove at the back of the camshaft is below an imaginary center line
Scheme 73
Install new O-rings around the spark plug wells at the cylinder head.
Apply liquid gasket 1161 059 to the camshaft cover.
Use roller 9512767 . The surface must be covered without any excess .
Note. Make sure that no liquid gasket gets into the oil channels.
Scheme 74
Lubricate the camshaft lobes, the camshaft bearing surfaces and the tappets.
Install the camshaft cover.
Install press tool 9995454 (2x).
Tighten the camshaft cover screws alternately, keeping it parallel to the cylinder head using the press tools.
Install the intake manifold and lifting eyes, tighten screws from the middle and outwards.
Remove the press tools.
Install
- the variable valve timing (VVT) solenoid. Use a new gasket
- the spark plugs. Tighten to 30 Nm .
- the hose for water-heated crankcase ventilation to the thermostat housing. Tighten the clamp.
Connect the connector for the engine coolant temperature (ECT) sensor.
Install the inlet pipe for the coolant pump on the cylinder head. Use a new gasket.
Note. Apply thread sealant, 116 056 to the screw threads.
Install the screw for securing the coolant pump intake pipe to the cylinder block.
Scheme 75
Install
- new gaskets.
Lift and install the manifold and turbo.
- the nuts and washers holding the manifold to the cylinder head
- the heat deflector plate above the manifold
- the upper turbocharger (TC) coolant pipes. Tighten the clamp on the rubber hose.
- the pipe screws for the coolant pipes. Use new seal washers. Tighten to 26 Nm .
- the oil pressure pipe
- the pipe screw holding the oil pressure pipe to the turbocharger (TC). Use new seal washers. Do not tighten!
Lubricate the studs on the turbocharger (TC). Use paste 116 1408 .
Install the front exhaust pipe onto the turbocharger (TC). Use new nuts. Do not tighten!
Scheme 76
Use drift 9995450 .
Lubricate the surface of the seal that the camshaft rotates against.
Press in the seal until the drift bottoms out.
Note. If there are grooves on the camshaft, the seal can be pressed in a further 2 mm: Reverse the sleeve.
Install camshaft adjustment tool 9995452 at the rear of the camshafts.
Ensure that the screws retaining the adjustment tool to the camshafts and the screws holding the tool together are well tightened.
Scheme 77
Use drift 9995718 for camshaft with variable valve timing unit and drift 9995719 for camshaft without variable valve timing unit.
Lubricate the surface of the seal that the camshaft rotates against.
Use the variable valve timing unit / timing belt pulley mounting screws. Tighten the screws until the drift bottoms out.
Remove the drift.
Install the screw holding the inner timing cover to the cylinder head.
Tightening torques
Note. For tightening torques not in the text, see Tightening torque.
Scheme 78
Remove the blind cover plug.
Turn the crankshaft clockwise slightly.
Install the crankshaft stop 9995451 . Ensure that it bottoms out against the engine block.
Turn the crankshaft counter-clockwise until it stops against the crankshaft stop.
Check that the marking on the crankshaft timing gear pulley corresponds with the marking on the oil pump.
Note. For tightening torques, see: Tightening torque.
Removing the torque bracket
Note. As the illustrations in this service information are used for different model years and / or models, some variation may occur. However, the essential information in the illustrations is always correct.
Scheme 79
Remove
- the engine stabilizer brace
- the charge air pipe (only turbocharged (TC) engines)
- the screw for the dip stick pipe (6 cylinder automatics only)
- the oil filler cap
- the cover over the ignition coils
- the torque bracket.
Scheme 80
Install
- the torque bracket. Tighten the screws (A). Tighten to 50 Nm
- the screw for the dip stick pipe (6 cylinder automatics only)
