Oil pan and oil pump

Instructions: If during engine repair a large amount of metal shavings and other wear products are found in the engine oil, this may indicate damage to the connecting rod or main bearings of the crankshaft. To avoid subsequent damage, after repair work it is necessary to: thoroughly clean the oil channels, replace the oil injection nozzles, replace the oil radiator, replace the oil filter. The oil level should not exceed the "max" mark on the dipstick. Otherwise, the catalyst may be damaged!

Lower Oil Pan Tightening Sequence

Tighten bolts -1...20- in 3 stages.

1 - Tighten the bolts by hand.
2 - Tighten the bolts to 8 Nm.
3 - Tighten the bolts by 45°.

Upper Oil Pan Tightening Sequence

Tighten bolts -1...14- in 3 stages.

1 - Tighten the bolts by hand.
2 - Tighten the bolts to 15 Nm.
3 - Tighten the bolts by 90°.

Oil separator - tightening torque

Tighten the bolts in sequence -1...9- to a torque of 9 Nm.

Removal and installation the oil separator

Remove the sound insulation. Unscrew bolts -1...9- and remove the oil separator.

Caution: Risk of contamination of the lubrication system. Cover the opening with a clean cloth.

Installation

Instructions: Replace gaskets and sealing rings. All hose connections must be secured with clamps that match those installed at the factory.

Installation in reverse order, taking into account the following: Tighten the bolts in the sequence -1...9- with a torque of 9 Nm.

Removal and installation the oil pump

Remove the lower part of the oil pan. Remove the oil separator "arrows".

Instructions: The following steps should be carried out in one working step, for this 2 mechanics are required.

Unscrew the "arrow" bolts and remove the oil pump.

Pull back the chain tensioner using the "T10118" mounting tool and remove the oil pump with the second mechanic.

Installation is carried out in the reverse order, observing the following. Before installing the oil pump, check the mesh in the inlet pipe and oil channels for contamination. Check the presence of both installation bushings for centering the oil pump. Replace the oil separators.

Instructions: The oil separators have plastic protrusions that are deformed when tightened. This ensures a gap-free fit of the oil separator and the absence of noise. Therefore, oil separators should always be replaced.

Motor oil

Filling volumes:

With oil filter 4.7 l.
Without oil filter 4.2 l.

Checking the oil level

The oil level must not exceed the maximum mark, otherwise there is a risk of damaging the catalytic converter!

Verification conditions

The engine oil temperature is not lower than 60°C. The car is on a flat horizontal surface. Wait a few minutes after stopping the engine for the oil to drain back into the pan.
