Scheme 377
Turn the crankshaft counter-clockwise (viewed from the rear of the engine) until the piston in cylinder 1 reaches top dead center (TDC).
Continue turning counter-clockwise until the piston in cylinder 1 is approximately 2-3 cm (0.79 - 1.2 in) before top dead center (BTDC).
Install the crankshaft stop 9995451 . Ensure that it bottoms out against the cylinder block.
Now turn the crankshaft clockwise (viewed from the rear of the engine) until the crankshaft counter-weight is in contact with the crankshaft stop.
Scheme 378
Install a new cylinder head gasket .
Install the cylinder head.
Use new screws .
Lubricate and install all the screws.
Tighten the screws in the following order. Tighten the screws alternately from the middle and outwards.
- 20 Nm (15 lb.ft)
- 60 Nm (44 lb.ft)
- Angle-tighten 130° . Use protractor «9512050»(/volvo/c70/i-1997-2005/remont/oem-general-information/#special-tools) .
Scheme 379
Lubricate the valve guide wells.
Install all valve lifters.
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 380
Install new O-rings around the spark plug wells at the cylinder head.
Apply liquid gasket 11 61 059 to the camshaft cover. The surface must be completely covered without any excess. Use roller 9512767
Note. Ensure that no liquid gasket gets in to the oil ducts.
Scheme 381
Lubricate the camshaft lobes, the camshaft bearing surfaces and the valve lifters.
Install the camshaft cover.
Install press tool 9995454 (x2).
Draw the camshaft cover alternately down, keeping it parallel to the cylinder head with press tool
Install all the screws and tighten.
Remove the press tools.
Install the variable valve timing solenoid with a new gasket. Tighten.
Scheme 382
Use drift 9995718 at the camshaft where the variable valve timing unit is to placed and drift 9995719 at camshafts without variable valve timing.
Lubricate the surface of the seal that the camshaft rotates against.
Tap in the seal until the drift bottoms against the end of the camshaft.
Scheme 383
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, by reversing the sleeve.
Scheme 384
Use camshaft adjustment tool 9995452 . Separate the camshaft adjustment tool into two units.
Note. The camshafts must not be turned more than is listed in the text below. The valves may be damaged!
Install the exhaust camshaft section of the adjustment tool. Counterhold the adjustment tool and screws it into place at the rear of the camshaft.
Screw the adjustment tool sections together into one.
Check that the screws retaining the adjustment tool to the camshafts and the screws holding the tool together are well tightened.

Tightening the intermediate section
Install the two old screws for the flywheel and carrier plate at the rear edge of the crankshaft.
Lift these and the front of the crankshaft.
Carefully position the crankshaft in the block.
The crankshaft must not be turned before the intermediate section has been torque tightened. Position the intermediate section.
Lubricate and install all the screws.
Note. Use new M10 bolts.
Install the intermediate section and the screws on the exhaust side at bearing recesses 2 and 5.
| CAUTION | The M8 bolts on the exhaust side have two different lengths. |
Pull down the intermediate section.
Tighten the screws in the following order
| 1. All M10 screws 20 Nm |
|---|
| 2. All M10 bolts 45 Nm |
| 3. All M8 bolts 24 Nm |
| 4. All M7 bolts 17 Nm |
| 5. Angle-tighten all M10 screws 90° |
Tighten the screws in sequence from the center and outwards.
Tightening the connecting rod cover
Install the cover. Check that any markings correspond.
Lubricate and install new seals. Tighten in two stages
Tighten the connecting rod cap. Acc. to Tightening torque
Check that the connecting rod can be moved sideways.
Note. The crankshaft must not be rotated before the connecting rod cover has been tightened.
